The paper presents a new simulation method for airbags with multiple compartments. In recent years many accidents happened with passengers that were out of position (OOP) when their airbag deployed. Therefore new safety regulations ...

This paper gives after a short introduction a more detailed overview about Model Assembly/Pre-Processing and Results Data Management/Post-Processing.

Tighter markets and tougher competition forces users of IT infrastructure to get the maximum speed and shortest time-to-result out of existing and cost-optimized hardware. With the introduction of LS-Dyna MPP version, new ways to use ...

This paper presents a new preprocessor for the assembly of independently meshed car body parts. The assembly process gains more and more importance in the preprocessing of crash-worthiness simulations. It is desirable to take ...

Since the first applications of Finite Element Analysis (FEA) in automotive design this technology has gone a long way to become a standard tool fully integrated in the design process of automotive industry. Strongly promoted by ...

The meshing, modeling and evaluation of LS-DYNA crash models for vehicle crash simulations is constantly subjected to an increase in complexity, since the model sizes grow, several vehicle variants are instanced from one single CAE ...

There is always a certain amount of springback deformation in a metal forming process. The high strength steel is becoming a more attractive choice for many applications when low weight of the structure is of importance. One major ...

This paper presents the results of applying the finite element method to calculating the spring back of an automotive hood assembly, and its application to the functional build method. The assembly was comprised of six individual ...

Manufacturing process simulation using finite element techniques has immensely contributed to ensuring the success of concurrent design methodologies. However, Finite Element Methods (FEM) is computationally expensive and consequently ...

The authors would like to present the whole procedure of using dynamic explicit finite element method to aid multi-stage miniature stamping die design. How to cost down and time saving are the key issues for tool maker in Taiwan. It ...
