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 ...

The purpose of this project is to improve the development process of vehicle safety systems by introducing a new analytic approach. Today the development of vehicle safety systems, especially the airbag design process, requires many ...

This paper describes geometry parameterization of turbine blade fir tree root prepared in LS-Prepost. The generated FE model utilizes LS-OPT in optimization loop. Simulation results of LS-DYNA implicit solver were used to extract ...

When deep drawing the parts with complex geometry, changeable thickening can occur in the flange area. Extreme thickening of the part flange will cause pressure peaks at the contact surface between blank holder and part. This ...

Dome reversal pressure test is one of crucial quality tests required of such products as beverage cans. It gives information about resistance of a bottom in conditions of increased internal pressure. The information is important both ...

Statistical studies showed that the chin bar of full-face helmets is the region with the highest number of impacts. In an Australian research fifty percent of severe impacts took place to the front of helmet and forty percent of these ...
