As EVs become more widespread, safety concerns are increasingly important for OEMs, consumers and regulators. Owing to the risk of thermal runaway in an EV crash incident, a full Multiphysics battery analysis is required to capture the mechanical deformation that triggers internal shorting and thermal runaway. This is helpful in knowing the mechanical design limits and designing vehicles with good crashworthiness while balancing the need to lightweight EVs as car companies strive for better range. LS-DYNA, because of its coupled multi-physics solvers, offers advantages in simulating electro-thermo-mechanical behavior of the battery without data transfer between different physics. Ansys developed a simulation workflow from battery cell to vehicle level (in partnership with universities and industry test labs) to validate key pieces using physical test data for automotive pouch cells. LS-DYNA models were calibrated and subsequently validated against cell experimental data. Multiphysics models that captured a battery cell’s electrical, mechanical and thermal behaviors were then to used to scale up in a proof-of-concept simulation of full vehicle crash. Ansys has partnered with George Mason University’s Center for Collison Safety (CCSA) to incorporate battery models into a full vehicle validated crash model. Ansys has tested cells (at our internal Ansys labs or through test partners) that CCSA extracted from a commercial VW ID4 EV to build battery cell models and module level models. The ongoing work to date will be discussed and used as an example to demonstrate the battery safety workflow in an EV.

In recent years, the application of plastic in automotive parts has been expanding as a replacement for steel plates, aiming for greater shape flexibility and weight reduction. Among plastics, fiber-reinforced plastic with glass fibers as reinforcement exhibits anisotropy, where the strength characteristics vary depending on the orientation of the fibers. To perform highly accurate crash simulations, it is necessary to reproduce this anisotropy in the LS-DYNA model. To reproduce this anisotropy, it is well known to conduct resin flow simulation in advance to obtain fiber orientation information and map it to the LS-DYNA model. However, performing resin flow simulation requires mastering advanced specialized software, knowledge of plastic molding, and a long working time, making it not easily accessible. Therefore, we developed a system that allows anyone to easily and quickly reflect the anisotropy of fiber-reinforced plastic in the LS-DYNA model by using a surrogate model of resin flow simulation as the core, along with a super-fast mapping tool and an intuitive GUI. This resulted in a 99% reduction in man-hours compared to conventional methods. Furthermore, the model combining this method with MAT_4A_MICROMEC showed improved reproducibility of strength characteristics compared to the isotropic MAT_SAMP-1 applied model.

Heart disease is among the leading causes of death in the Western world; hence, a deeper understanding of cardiac functioning will provide important insights for engineers and clinicians in treating cardiac pathologies. In this paper we will concentrate on the electrophysiology (EP) part of the physics, which describes the propagation of the cell transmembrane potential in the heart. In LS-DYNA, EP can be coupled with the mechanics and the fluid solvers for a Multiphysics simulation of the heart, but pure EP is also often used to investigate complex phenomena such as cardiac arrhythmias or fibrillations. The gold standard model for EP is the “bi-domain” model, along with the slightly simplified “mono-domain”. These were introduced in LS-DYNA a few years ago. They give very accurate predictions, but the associated computational expenses are significant, which can be an issue for patient-specific predictions, for example, cardiac activation patterns for complex procedures such as cardiac resynchronization therapy (CRT). In this paper we introduce new computationally efficient eikonal and reaction-eikonal solvers. The eikonal method is very general and describes the propagation of a wavefront in a medium with given propagation velocities. The eikonal solver will be presented and different examples will be shown.

This approach enables simulations on accurate geometries and provides high continuity, which is particularly beneficial for thin-walled structures like shells. Local mesh refinement is a well-established technique in standard FEA to improve accuracy while keeping computational costs manageable. However, its transfer to isogeometric shells is non-trivial, particularly in the presence of trimming, which is a common feature of CAD models in boundary representation (B-Rep) [2]. The integration of trimming and local refinement in an efficient and robust manner is a key step towards many industrial applications of IGA, such as sheet metal forming simulations. In this contribution, we present recent developments on the integration of trimming and local refinement for isogeometric shell analysis in LS-DYNA. We employ both Locally Refined B-splines (LR B-splines) and Truncated Hierarchical B-splines (THB-splines), which break the tensor-product structure of conventional B-spline patches and enable local refinement without introducing meshlines across the entire patch. These advanced spline technologies are integrated using the BEXT (Bézier extraction) format, which facilitates the use of general spline structures in LS-DYNA simulations. We address algorithmic challenges and interface aspects, and we demonstrate the approach with trimmed, locally refined shell models in the context of sheet metal forming. The presented work lays the foundation for efficient isogeometric shell analysis in LS-DYNA incorporating local mesh refinement. It contributes to closing the gap between CAD and analysis and enables high-fidelity simulations for complex engineering applications. REFERENCES [1] T. Hughes, J. Cottrell, and Y.

AC contactors can exhibit reopening behavior during AC current zero-crossings. Shading coils are used to generate retarded eddy currents that help maintain closure. This study employs LS-DYNA’s multiphysics solver to simulate the coupled electromagnetic and mechanical dynamics of AC contactors with shading coils. The model accounts for nonlinear ferromagnetic materials and variable air gaps due to part motion. A generic geometry, based on published literature, ensures broad relevance. Simulation results confirm that optimized shading coil configurations significantly enhance closure stability.

Autonomous driving systems and their functionalities need to be evaluated thoroughly in order to ensure their safety. This can only be done efficiently at any stage of the development process by using virtual twins of these systems. We seek to evaluate such physical sensor models of automotive radar systems. We focus on Ansys AVxcelerate SensorsTM that we run in co-simulation with IPG CarMaker. We are interested in how we can parameterize such a model according to an actual sensor from the Valeo product portfolio and use it in virtual testruns. Simulation results for various relevant test cases including multi-path propagation are shown and compared to real measurement data and analytical computations.

This work presents a streamlined and highly automated methodology for deriving forming limit curves (FLCs) using 3D digital image correlation (3D-DIC) in combination with the LINOVIS testing system. Nakajima-type tests are conducted on downscaled specimens to simplify handling and material extraction. A pneumatic clamping system ensures high throughput and repeatable boundary conditions. The test setup accommodates a wide range of strain rates and forming speeds – from quasistatic up to more than 3m/s - using a single machine configuration. Two high-speed cameras capture the local strain evolution during deformation, enabling precise evaluation of the forming behavior. The 3D-DIC data is processed automatically to extract forming limit curves with minimal user intervention. Finally, the resulting data is seamlessly integrated into an automated workflow to generate complete material cards for use in metal forming simulations. This approach significantly reduces manual effort and enhances the reliability and reproducibility of material characterization for forming process design.

Percutaneous pulmonary valves (PPVs) are used to replace native diseased pulmonary valves. This work presents a framework for patient-specific PPV fluid-structure interaction (FSI) simulation. Geometrical models of the pulmonary arteries and bifurcation of four patients who received a PPV at Great Ormond Street Hospital for Children (UK) were reconstructed and assembled to a model of the Melody valve (Medtronic). FSI simulations were conducted by coupling LS-DYNA ICFD and structural implicit solvers. Patient-specific boundary conditions were set up. Simulations captured PPV hemodynamic patterns and successfully computed transvalvular pressure drops in accordance with clinical measurements, proving the FSI framework to be a valid tool for the patient-specific assessment of PPV biomechanics.

Over the past few years, the IGA capabilities in LS-DYNA have been continuously extended and improved, also facilitated by a close collaboration with academia and industry. This culminated in full vehicle crash simulations of a body-in-white modelled with hundreds of trimmed NURBS shell components [1]. Motivated by the achievements with shells and the increasing usage of (large) casting components in the automotive industry, the concept of trimmed B-Spline solids was recently implemented in LS-DYNA [2,3]. These trimmed B-Spline solids enable a fast and simple model generation, a feasible explicit time step size, decoupling of geometry and mechanics and thus new attractive possibilities for crash analysis of casting components. In this contribution, we present practical studies of IGA shell and solid models with a focus on new capabilities, material calibration, damage and failure modelling, and the comparison with conventional FEA models in terms of accuracy and numerical efficiency. We furthermore demonstrate the wide range of IGA capabilities in LS-DYNA through a variety of industrial application examples. REFERENCES [1] F. Bauer, T. Yugeng, L. Leidinger, S.

For advanced composite design and analysis, predictive multiscale modeling tools are transformational by capturing the influences of manufacturing process-induced microstructures on the macroscopic mechanical behaviors. Traditional simulation methods, such as FEM-based computational homogenization techniques, are effective in material multiscale modeling, but the high computational costs cannot be afforded in industrial applications. To accelerate multiscale simulations, a physics-informed AI technique named DMN (Deep Material Network) has recently been developed. Through offline training using linear elastic material data, DMN can learn the essential physics hidden in the representative volume elements of composites. In the online prediction stage, DMN is highly effective in predicting nonlinear composite responses under arbitrary complex loading conditions, which is promising for multiscale structural analysis and material design. Under an integrated computational materials engineering framework, this AI technique has been implemented for multiscale structural analysis of short fiber-reinforced composites, where injection molding data are integrated with LS-Dyna models to consider the effects of heterogeneous fiber orientation and volume fraction distributions. We will discuss the main features of LS-Dyna DMN and present user case studies to demonstrate the effectiveness of this AI-empowered multiscale simulation technique.

Reinforcement Learning (RL) is a key technology for controlling complex, dynamic systems. Yet in industrial practice, a fully integrated infrastructure—from training to deployment—is often missing. Tools are manually connected, workflows individually structured, and results laboriously documented, increasing time and error risks. This modular platform closes that gap. It enables structured, reproducible, and efficient RL workflows—both in simulation and on real hardware. The unified architecture integrates known tools like Gymnasium. Users plug in custom environments; the platform handles logging, evaluation, training, and model management. Its main advantage: seamless transferability from simulation to real-world systems. While currently focused on RL, the architecture can also support classical ML approaches (e.g., PyTorch). It is aimed at engineers and researchers implementing intelligent control—from digital twins to physical assets.

This work revisits the method proposed by (Lo and Ling, 2000), which decomposes the element stiffness matrix into constant and higher-order parts. Preserving the constant part ensures element consistency, while the method specifically treats the higher-order part responsible for locking behavior. The proposed approach is extended to support explicit time integration scheme and it is integrated into LS-DYNA for ten-node tetrahedral elements with five integration points as a user-defined isotropic linear elastic material model. A series of numerical simulations validates the effectiveness of the proposed method.

DIEM is a popular model for the prediction of failure in LS-DYNA. However, this model has been mostly used for aluminum and steel sheets which are typically modelled with shell elements. With the increasing usage of aluminum die castings in car design, the interest in modeling with solid elements in car crash simulations has significantly increased. With three different mechanisms for damage initiation (ductile, shear and instability), DIEM has been conceived having the plane stress assumption in mind, which is adopted in standard shell element formulations like ELFORM=2 and 16 in LS-DYNA. In this presentation, we will highlight how DIEM can be used for solid elements, what are its features and limitations and how to use it properly for car crash simulations in LS-DYNA.

Accurate stress prediction in fiber-reinforced laminates is crucial for anticipating damage. Standard shell elements, though computationally efficient, lack accuracy due to simplifying assumptions. Conversely, solid element discretizations, while accurate, are computationally prohibitive. To bridge this gap, we apply higher-order 3D-shell elements, implemented as a user-defined element in LS-DYNA. Unlike standard shells, these elements can capture cross-sectional warping and a fully 3D stress state. Our contribution highlights them as a viable approach to achieve more reliable stress predictions for composite structures, crucial for robust design and damage assessment, without the prohibitive cost of fully 3D discretization. We acknowledge the funding by the BMWE (19S22006K).

The force levels that must be taken care of in the event of a car crash have been growing steadily with increased vehicle mass and higher safety requirements over the years. This would be true even without the shift towards battery power since the weight of equipment like infotainment and cables has increased while limiting the total vehicle weight for energy efficiency. It has driven the need for higher strength materials in body structures. Higher strength materials are often more brittle and with the need to optimize the structures it calls for accurate material modeling including failure prediction. Production efficiency is another important aspect in the choice of materials. This presentation intends to show how the Generalized Incremental Stress State Dependent Damage Model (GISSMO) can be combined with the common LS-DYNA material models to obtain accurate modeling of popular material types in vehicles. Examples of material modeling for dual and complex phase steels, ultra-high strength steels, aluminum die castings, aluminum sheets, aluminum extrusions, unreinforced plastics and reinforced plastics will be given together with some important aspects of the modeling methods.

This paper presents the implementation of immersed interface techniques within the Incompressible CFD (ICFD) solver in LS-DYNA for fluid-structure interaction (FSI) simulations. Immersed methods offer several advantages: they streamline pre-processing, eliminate mesh distortion caused by large structural motions, and enhance robustness in scenarios involving complex contact. However, these benefits often come at the cost of reduced near-wall accuracy, suggesting that hybrid approaches combining body-fitted and immersed methods may offer the best of both worlds. Two approaches are discussed: the Resistive Immersed Implicit Surface (RIIS) method [1] and a novel formulation based on discontinuous finite element functions [2]. The presentation will cover the theoretical background of each method and provide practical guidance on model setup, including pre-processing steps and post-processing considerations within LS-DYNA.

The Smoothed Particle Galerkin (SPG) method has been developed in LS-DYNA for large deformation and failure analysis of ductile materials. Compared to the finite element method (FEM), SPG has been demonstrated to provide greater accuracy and robustness in modeling manufacturing processes such as joining, cutting, grinding, and drilling. However, as a particle-based Lagrangian method, SPG relies on frequent neighbor searching, particle integration, smoothing operations, and explicit time integration schemes designed to enhance numerical stability and accuracy. Consequently, the overall computational complexity of SPG could be an order of magnitude higher than that of conventional FEM for the exact domain discretization. Furthermore, the massively parallel processing (MPP) communication overhead associated with SPG increases significantly, particularly under conditions of severe material flow and separation, such as in screwing and grinding simulations. The rapid evolution of modern GPUs provides a strong alternative for accelerating SPG computation. The massive computational power, with tens of thousands of cores, large memory capacity, and bandwidth available in mainstream single-GPU systems, fulfills the demands of typical manufacturing process models using SPG. This presentation will cover the current progress of LS-DYNA SPG GPU development, including: • A moment-consistent SPG (MC-SPG) formulation rewritten in C++ with support for various GPU architectures, featuring algorithms and implementation frameworks highly optimized for GPU acceleration. • Integration of the SPG GPU code as a dynamically linked library (DLL) within LS-DYNA. The current coupling interface supports (1) TIED and NODES_TO_SURFACE contacts with FEM parts running in LS-DYNA, (2) sub-cycling for SPG parts, which typically run at smaller time step sizes, and (3) d3plot output for SPG parts. • Introduction of a new keyword to activate GPU offloading for SPG parts. • Supported keywords of material models and boundary/initial conditions for SPG parts. • Benchmark results demonstrating the accuracy and performance improvements of this new GPU development compared to the LS-DYNA MPP versions of FEM and SPG.

Automotive parts are often manufactured using multiple forming processes, including Blanking, Drawing, Trimming and flanging and which often involves significant plastic deformation in the components. This affects the stiffness and strength of the component due to strain hardening and sometimes multiple iterations need to be performed varying the process parameters to achieve good quality parts. As a next step, not considering the prestress and thinning effects could result in inaccurately predicting the Vibrational performance of the part. Ansys Forming has been used to simulate the Multistage forming process, and the process parameters are optimized through optiSLang. The prestress results are exported to both LS-DYNA and Ansys Mechanical which are used to calculate the modal frequencies. The current workflow could be extended to other kinds of analysis like failure analysis of the component.

In this paper, a modified 2005 NUMISHEET Crossmember was used to demonstrate SimAI’s use cases in stamping sheet metal formability prediction. The AI model is trained with 49 DOEs of LS-DYNA stamping simulation consisting of various die and punch radii changes. The formability results from the DOEs produced both failure and wrinkles, which is of interest in the SimAI prediction study. Use CASE A focuses on prediction of thickness, strain and FLD in a “one-step” fashion. The last state of the incremental LS-DYNA simulation results on the blank are used to build the AI model. New part geometries are used to predict formability based on the trained model. This case consists of formability prediction with new part geometries on an AI model trained with trimmed panels, and prediction of new part geometries on an AI model trained with drawn panels. Use CASE B focuses on transient prediction of thickness and deformation. All states of 49 DOEs (a total of 490 training/test data sets) were used to train the AI model. Prediction results are discussed and SimAI application strategies in Stamping Die Engineering are discussed.

There are many challenges with integrating radars in a vehicle. One of them is the positioning and installation. How you angle them will affect the covered field of view and can affect AD/ADAS functionality. The height of the sensors can affect scattering from road and road curbs. Installation behind fascia and paint affects the attenuation and phase, leading to a weaker signal return as well as angle errors. When testing in vehicle there is often a lack of ground truth as well as limited repeatability, not to mention that it’s expensive and time consuming. Combining Ansys HFSS and Ansys AVxcelerate we can in a controlled environment see how the position and installation affects the radar performance and create better radar configurations for tomorrow’s vehicles.

The results of the current work stem from a project with Mercedes AG on aluminum die cast wheels for small overlap crash scenarios. Such materials are extensively used in the automotive industry for mechanical applications due to characteristics like excellent strength-to-weight ratio and corrosion resistance. The repeatability of the die casting process ensures high-quality, complex geometries with tight tolerances, enhancing the performance and efficiency of automotive mechanical systems. Additionally, aluminum’s recyclability aligns with the industry’s sustainability goals, making it a preferred material for modern automotive engineering. Especially in the case of crash applications, aluminum has gained the spotlight over the years as a crucial material to achieve lightweight designs. However, aluminum die castings exhibit complex mechanical behavior when subjected to large loadings, eventually leading to material rupture. For instance, inhomogeneities in the material stemming from the manufacturing process pose a challenge where variables like porosity, flow length and solidification time play a significant role. In this contribution, we will present modeling strategies currently used for the simulation of such materials in crash applications. Solid elements are employed due to the complex geometries involved. Furthermore, the use of an unconventional failure surface within GISSMO in LS-DYNA and the stress-damage coupling to capture the semi-brittle material behavior up to fracture is presented. Evaluating DIC measurements clearly shows inhomogeneous behavior of the deformation of the material. Our results show that the use of stochastic tools is helpful to predict material behavior, provided that the geometrical effects are taken into account. The employed modeling strategy proves to be effective in properly predicting not only coupon tests but also large-scale component tests without using any stochastic measure.

Ensuring the performance and safety of adhesive bonds under mechanical, thermal and hygroscopic loading is a key challenge in many engineering applications. We present a simulation method in LS-Dyna to predict the lifetime of hygro-thermo-mechanically loaded adhesive joints. The approach addresses coupled problems involving mechanical deformation and moisture diffusion. Adhesive behavior is described by a linear viscoelastic model using the timetemperatureconcentration superposition principle. To capture degradation, the model is extended with a local damage formulation accounting for creep, fatigue and hygroscopic damage. Numerical examples demonstrate the model’s predictive capabilities.

This paper aims to provide an overview of LS-TaSC, highlighting its key features, capabilities, and applications. One of the key strengths of LS-TaSC is its ability to handle multidisciplinary topology optimization with constraints, which integrates multiple disciplines such as static analysis, NVH, impact, or any combination, simultaneously in an optimization problem, making it an invaluable resource for engineers to explore innovative design solutions that meet various design requirements across different disciplines. By leveraging the software’s capabilities, several application examples in automotive part design are provided to demonstrate its ability to tackle complex challenges associated with crash and contact conditions. At the end, highlights on the new features of the latest version are summarized, including enforcing the minimum and maximum part feature thickness, supporting to display and dump topography design results of shell structures in 3D format based on its final thicknesses, supporting the keyword *ELEMENT_SOLID_ORTHO, supporting the I10 formatted keyword files, and enabling to include the long length file name of the file in the *INCLUDE keyword.

IEC 63187 'Systems engineering – System safety – Complex systems in defence programmes' is a next to be published standard that brings system safety inside systems engineering though ISO/IEC/IEEE 15288:2023.

That system safety framework defines some specific safety artefacts and a measure of importance scheme including the link to the existing realisation standards, and it also highlight the importance of candidate architectures, risk trade-off and an iterative and recursive approach.

Directional deformation processes like rolling and extrusion cause anisotropic mechanical properties due to reoriented crystallographic grains (texture). This anisotropy significantly affects processes like deep drawing. While numerical simulations can account for texture-dependent defects in forming simulations, many FE methods neglect evolving anisotropy or use fixed textures. Often this is the case because full-field crystal-plasticity (CP) FE models are computationally too demanding for industrial-relevant part sizes. This presentation shows the use of the visco-plastic self-consistent (VPSC) model as an efficient way of modelling a metal’s developing texture and mechanical response. Coupling VPSC with LS-DYNA enables modelling developing texture in large-scale metal forming.

Restraint systems have traditionally been developed based on the anthropometric characteristics of the average male, potentially reducing safety for individuals with different body proportions. Expanding simulations coverage to a wider range of body types is essential, but current Human Body Models (HBMs) lack high anthropometric diversity due to the high cost and time required for development. To address this limitation, BETA CAE Systems introduces in ANSA the HBM Scaling Tool designed to adapt existing HBMs to variant anthropometric profiles. A comparative analysis is carried out between two human body models (HBMs) defined using LS-DYNA keywords: the baseline THUMS AM95 and a THUMS AM50 model scaled to AM95 anthropometrics using the Scaling Tool. The comparison focuses on multiple criteria, including mass distribution, center of gravity (COG), body morphology, bone dimensions, and elements quality. The scaled model validation involves conducting sled test simulations with various restraint systems, meticulously configuring LS-DYNA keywords for accurate testing. These simulations are closely modeled after Vezin et al.'s (2001) study. Acceleration in the head, spine, and pelvis—are analyzed, along with major principal strain patterns in the ribs. The results are compared with those from the original THUMS AM95 model and available experimental data from the Vezin study. This research highlights how the scaling approach proposed by BETA CAE Systems enables more representative occupant simulations, supporting the development of restraint systems better suited to a diverse population.

In recent years, artificial intelligence (AI) has begun to significantly influence the field of computer-aided engineering (CAE). Technologies like Ansys-SimAI have been successfully deployed to develop surrogate models of complex finite element (FE) simulations, enabling rapid system behavior predictions. Despite these advancements, the conventional iterative design process remains slow due to the time-intensive task of generating new design variants. To address this limitation, Ansys has introduced a generative design solution that automates the creation of design alternatives. Starting from seed geometries, the tool generates hundreds of new, physically plausible variants within the original design space. When combined with SimAI, this forms a comprehensive pipeline for rapid design generation and evaluation, enhancing product development efficiency. This paper demonstrates training a SimAI model to predict vehicle behavior under side impact loading using high-fidelity LSDYNA simulations as database. The sill in-lay designs from these simulations serve as seed geometries for the generative design tool, which then creates new geometries within physical constraints. Both tasks are completed in seconds, showcasing AI's potential when combined with legacy CAE data to accelerate product development cycles and improve design efficiency and innovation.

Human Body Models (HBMs) are used to study injury-biomechanics and vehicle safety. Traditional active HBMs use 1D Hill-type elements to represent muscles but face key limitations, such as subjective routing, inaccurate moment arms, and inability to model lateral expansion during contraction. As part of the CARpulse project, this method introduces a hybrid modelling approach using LS-DYNA. It combines 1D elements for active behavior with 3D solids for passive mechanics, coupled via shared nodes. This enables realistic stress transfer and increased stiffness during activation. The modular setup allows future integration of controllers based on joint angles or muscle lengths, supporting biofidelic and efficient goal-directed motion simulation.

BLB Engineering
The objective of this study is to assess the performance of a L7 Class electric vehicle (EV) in a range of crash scenarios. The tests encompass a range of scenarios, including frontal crashes into a rigid wall, a deformable barrier, a road barrier, and a road blocker bollard. Given that no mandatory safety requirements have been established for this category of vehicle, the necessity for such a requirement is called into question. The aforementioned crash test scenarios were simulated using ANSYS LS-DYNA software, featuring two distinct crash protection systems: a stationary prevention system and a replicable concept bumper system. An examination of the results of the collision tests reveals that the replicable bumper provides significant benefits, particularly in the case of low-speed impact collisions with a deformable barrier. In such instances, the bumper can be repaired without compromising the integrity of the main structure. The objective of this study is to underscore the significance of safety for this class of vehicles. In consideration of these types of collisions, the study will propose cotilion-based safety standards for future implementation.

4a engineering GmbH
Knowledge of the mechanical behavior of materials is essential for the simulation of dynamic load cases. In comparison to the real part performance, a realistic testing method for the material characterization should be used. Over the last years, 4a engineering GmbH developed the software solution VALIMAT®, which helps the user to calibrate FEM material models based on measurement data with a reverse engineering process. For the widely used material models automated workflows ´ÀUTOFIT` were defined. They state the necessary measurements and have parameterized material models and define how the parameters are optimized. These workflows though did not support the fitting of a failure model. The introduction of the ´AUTOFAILUREFIT´ feature automates this step and with that reduce the required time leading to a streamlined process. The present work showcases these automated features and the calibration approach for typical material classes used in the automotive industry under crash loading. Currently material and failure modeling in crash simulations typically deal with simple von Mises visco-plasticity (*MAT_024) and equivalent strain failure criteria. For the description of complex material behavior as an example in the case of unreinforced thermoplastics (like tension-compression asymmetry) *MAT_187/*MAT_187L are commonly used. In the present work, emphasis has been placed on using *MAT_ADD_EROSION failure models which can be added to other material models.

Protection of engineering structures against blast loading has gained significant attention in recent years. Steel is often favored due to its high strength, ductility, and formability, offering effective load-carrying capacity at relatively low cost. Plated steel structures are widely used and are often perforated—either by design or due to fragment impacts prior to the arrival of the blast wave. These perforations can significantly influence structural performance, making it essential to understand their effect under blast loading. Accurately predicting the response of such components requires advanced simulation tools capable of capturing complex fluid–structure interaction (FSI) and shock physics. The CESE solver, now available in LS-DYNA, offers such capabilities, but its performance must be validated against experimental data to ensure reliability in practical applications. In this study, numerical simulations are conducted to investigate the response of perforated steel plates subjected to blast-like loading. The results are compared with experimental data from the literature to assess and validate recent advancements in FSI modeling using the CESE solver in LS-DYNA. This work contributes to the development of accurate, efficient, and cost-effective computational methods for the design and assessment of blast-resistant structures.

Using the Ansys LS-DYNA CPG method, we have obtained results in which the gas front velocity and deployment behavior generally matched the test results using S-shaped airbags and simple curtain side airbags (CSABs) that have no vents or leaks. In this paper, we continue to verify the prediction of the airbag internal pressure, which is necessary for predictingthe injury of the occupant, using the simple CSAB. The results were qualitatively similar to those of the test, but there was a quantitative discrepancy, and the cause was discussed. In addition, the application of newly developed turbulent viscosity model showd partial improvement in pressure history. Furthermore, the simplified CSAB was deployed from a folded state, and the deployment behavior was compared with the test, showing good agreement.

The Generalized Incremental Stress-State dependent damage MOdel (GISSMO) is widely used in crash simulations to model the damage and failure of ductile materials. Since its inception, significant effort has been devoted to regularization schemes that minimize mesh dependence. However, regularization for arbitrary stress states remains a challenge. The work of Andrade et al. (2022) introduced a proportional loading strategy for element patches, i.e. loading with constant triaxiality. Building on this strategy, the present study proposes a new iterative scheme that ensures equal energy to failure for all mesh sizes in arbitrary stress states. The implications of the resulting regularization are investigated in virtual component tests. Sources: Andrade, F. DuBois, P., Feucht, M., Graf, T., Conde, S:, Haufe, A., 2022.

Recently, the trend of vehicle weight reduction is accelerating due to fuel efficiency and environmental issues, and in particular, in the material field, attempts are being made to apply high-strength steel of complex structure steel to vehicle weight reduction and parts weight reduction. In this study, a lightweight road wheel for commercial vehicles used in trailers, trucks, and buses was developed. In order to reduce the weight, shape optimization was first performed based on the shape of the existing mild steel wheel, and durability performance was compared and reviewed with the existing low-strength mild steel wheel to verify performance due to concerns about thickness reduction and rigidity reduction due to the application of high-strength steel. In particular, cooling performance and durability performance were improved by applying the drawing method to the vent hole. The newly developed wheel achieved a 15% weight reduction and showed the similar performance in rigidity and durability as the existing verified mild steel wheel.

In this contribution the isogeometric analysis (IGA) shells and solids technologies are applied for numerical simulations of experimental tests on a crash box and two aluminum profiles and compared to classical FE discretizations in terms of experimental results approximation and computational effort. The focus is on three loading scenarios: compression, bending, and axial load. For IGA solids, in addition to simulation results, such as simulation time, absorbed energy and added mass, the influence of the interpolation mesh structure on contact modeling and result quality is also examined. For IGA shells, the emphasis is on advantages of a better representation of the geometry of the crash and of the extruded profiles, as well as the assessment of contact behavior under axial loading. The study offers a detailed evaluation of the benefits of IGA for crash-relevant component simulations, grounded in experimental data.

To meet design and crash requirements in vehicle development, engineers must adapt and refine simulation models. Each model change is validated through new simulations, aiming for improved crash performance while avoiding unintended effects. Identifying and documenting all impacts - whether known or unknown - is critical. Comparing simulation outcomes manually is time-consuming, but machine learning can automate this by using a continually expanding database that captures crash behaviors from previous simulations. This database acts as a reference, flagging known but undesirable behaviors in new results. Efficient data compression reduces database size dramatically - for instance, from over 7 TB of raw data to just 14 GB - enhancing manageability. When engineers need to check if a specific deformation behavior has occurred across simulations, they can use geometric search. Through Model Order Reduction (MOR), deformation patterns are projected into a low-dimensional space, enabling fast similarity comparisons across all simulations and time steps. This allows engineers to quickly identify when and where similar behaviors occurred, such as early buckling or final deformations. Even with hundreds of crash simulations, searches take only seconds, supporting real-time, interactive analysis.

JFOLD is a software tool for simulation-based airbag folding in Ansys LS-DYNA. *AIRBAG_CPG is a new gas dynamics solver that shows great promise for deployment prediction through accurate simulation of gas flow within complex airbag structures. Curtain airbags are an important part of a vehicle’s safety system. Carefully folded to fit within the trim and roof side rail, they must deploy very quickly into the narrow gap between occupants and doors, once a side collision is detected. In this presentation we show how different folding patterns of one curtain airbag can be easily designed and optimized using the latest JFOLD features. The deployment performance of each fold pattern is then assessed using *AIRBAG_CPG, after validation of a baseline to physical tests.

EVs are necessary for the transition to sustainable mobility but require meeting stringent safety regulations. Critical aspects include evaluating battery safety risks to occupants during various crash conditions. This includes, but is not limited to, cell damage, short circuits or electrolyte leakage, which demands high fidelity mechanical modelling of cells and modules. This paper presents a methodology to represent cell swelling and assembly pre-loading in battery module simulations. Deceleration and crush simulations are performed to validate the proposed method by comparing with test data. The results highlight the need to include pre-loading in assessments to accurately represent the module stiffness, validated by improvements in relevant KPIs.

For ATDs the H-point locations are clearly defined within protocols, they can be measured in hardware and have a uniform/clearly defined position in their geometric design. Human Body Models however do not have H-Points, instead using the center of the acetabulum has been established as the best practice analogue to the ATD technology. However, measuring the acetabulum centers is difficult to do in volunteers in situ by using non-intrusive methods. Historically there have been no defined protocols how HBMs should be positioned in a seat, which can be seen as reasonable as how real occupants sit in a given seat can also vary. To investigate the effects of the seating procedure, a study is performed in which different HBMs and ATDs were positioned in a production seating environment using different methods to assess their H-Point locations. Contacts forces and other metrics were evaluated and compared between HBMs and ATDs to analyze possible sources of different behavior. For the ATDs the real physical measurements were available and used as a reference to establish a baseline truth position. Using only gravity settling, the H-point of the ATD remained higher than what was measured in hardware. This implies that the seat models are too stiff for positioning. The seating models used in this study have been validated for their behavior in crash, and so it is conceivable that quasistatic ergonomic stiffness may not have been considered. To seat the HBM to a qualitatively realistic position, the forces from the ATD gravity settling were compared to the forces used to achieve the measured position. This force-delta was then applied to the HBMs to achieve a more realistic seating position. For both the gravity settled position, as well as the realistic positioned occupant models, impact simulations were performed to see what the difference in initial H-point position had on the head kinematics as well as the seat belt forces.

The introduction of virtual testing protocols presents OEMs with new data submission and reporting requirements. But once the problem of data submission is overcome, the real challenge begins: how to achieve a five-star safety rating? Achieving good correlation between simulation and test is crucial – without good correlation in the validation loadcases, the virtual loadcases count for nothing and the overall score is low. The Oasys LS-DYNA Environment is a key part of many Ansys LS-DYNA workflows, used to ensure quality models and results. This paper explores how CAE teams are using tools to rapidly pinpoint problem areas in their simulations and identify the sources of poor correlation – enabling them to correct models, improve the robustness of designs, and maximise their safety rating.

This work presents a high-fidelity numerical modeling framework for simulating brittle geomaterials subjected to explosive loading, developed within the LS-DYNA environment. The approach centers on the application of the Johnson–Holmquist II (JH-2) constitutive model for rock-like materials such as sandstone, with model parameters calibrated through a combined program of quasi-static and dynamic mechanical testing, including Split Hopkinson Pressure Bar (SHPB) experiments. Simulation scenarios capture key physical phenomena such as detonation wave propagation, primary and secondary fragmentation, and reflected wave effects. Special attention is given to optimizing underground blasting processes using multiple strategies — including tile-based (layered) models, symmetry-based domain reductions, and simplified boundary conditions — to enhance computational efficiency and predictive capability while retaining physical realism. Comparative studies of penalty-based contact formulations, modeling methods (rock/high explosives) are performed to assess stability and numerical robustness under extreme dynamic loading and fracture. Model validation is conducted against experimental blast data, including pressure-time histories, particle velocity fields, and fracture zone evolution. The developed methodology enables systematic and cost-effective optimization of underground blasting strategies, with applications in mining, tunneling, civil protection, and defense engineering.

The rapid growth of AI applications has significantly increased the volume of simulation runs, especially for training AI models. While modern Simulation Data Management systems and IT infrastructure can store and access vast datasets, users typically only conduct basic model-to-model comparisons between successive versions. To address this limitation, a new database leveraging Principal Component Analysis (PCA)—a dimensionality reduction technique from unsupervised learning—was introduced at the previous NAFEMS World Conference. Continuously updated with new simulations, it enables automatic detection of novel behaviors by comparing recent runs with all prior ones. Key challenges such as mapping across different models, ensuring database performance, and capturing local effects were addressed. Responding to engineers' needs, the system was further enhanced to handle time history curves, enabling storage, compression, and anomaly detection within curve data. When deeper insights are needed, structural deformation patterns can be correlated with curve anomalies, allowing identification of both curve-to-curve and part-to-curve relationships. This empowers engineers to make design adjustments that improve system behavior. Additionally, the tool now supports similarity searches in time history data to identify simulations with comparable dynamic responses.
Parametric Design
Ensuring controlled abrasive powder delivery is fundamental for efficient dental prophylaxis. The design of powder reservoir significantly impacts performance, yet experimental assessment of design-related issues is challenging. To address this, an LS-DYNA simulation combining Discrete Element Method (DEM) and Computational Fluid Dynamics (CFD) was developed to replicate particle-air interactions. DEM parameters were tuned to match experimental powder behavior, while CFD calculates airflow dynamics. The simulation results were experimentally validated, confirming the DEM-CFD model's accuracy in predicting powder consumption within the reservoir. This simulation tool is therefore highly valuable for optimizing reservoir designs, leading to improved patient care and procedural efficiency.

IGA 3D for Bolt assemblies
The initial deployment of IGA for shell structures at Stellantis is delivering promising results.
Building on this success, solid elements will follow once solver capabilities and modeling techniques reach sufficient maturity. Bolt assemblies will be a first key application.
While 3D meshing of bolts improves assembly representation, issues such as mesh dependency (contact facet effects, mesh-dependent failure) and mass scaling remain challenging.
This study will address key topics:
1. Finite Element (FE) Representation: baseline results and limitations
2. IGA for Bolts:
- Mesh and grid sensitivity
- Material and failure model calibration
3. Next Steps:
- Integrate expected solver enhancements in LS-Dyna
- Define a scalable, automated deployment process for broader industrial rollout
