LS-DYNA’s origins and core-competency lie in its well-known contact Algorithms, which is very powerful and functional. In order to simulate the details in the contact zones of bolt connection of the magnesium stabilizer clamp under ...

Airbags are part of an important vehicle safety system, and the inflator is an essential part that generates a specific volume of gas to the airbag for a short duration of time. Recently, we have developed numerical models of ...

A new feature of random vibration analysis is available in LS-DYNA since version 971, which has been shown to be a powerful tool for the simulation of vibration shaker table test driven by power spectrum density (PSD). In particular, ...

In deep-drawing dies for steel sheet parts of car bodies huge masses are moved. To prevent vibrations, which occur by sudden acceleration or stopping of those masses, elastomeric tubular dampers [1] are used. The dampers are made out ...

Topology optimization considering transient nonlinear behavior of mechanical structures, e.g. automotive crash, remains a challenge in both the implementation as well as computational effort. In recent years, efficient optimization ...

This paper discusses some issues relevant to automatic crash model translation (conversion), based on SimTech experience. Automatic crash model conversion is in many ways similar to automatic language translation. The first level of ...

The requirements for energy efficiency and lightweight construction in automotive engineering rise steadily. Therefore a maximum flexibility of different materials is necessary and new joining techniques are constantly developed. The ...

The superior ductility and toughness of rubber-toughened polymers relies on microscale deformation and damage mechanisms such as void growth, shear yielding and crazing. In the present work, a micromechanical model for the inelastic ...

The high specific stiffness and strength, the ease of shaping as well as the great impact performance of layered fabric reinforced polymers encourage their diffusion in the automotive industry. In order to increase the predictability ...
