Currently, there are several material models implemented in LS-DYNA which are more or less capable to simulate a spot weld behavior under crash conditions. The material parameters for crash simulations are determined by comparing the ...

Pedestrian head impacts on windscreen are a potential source of pedestrian injury and form part of the EuroNCAP Pedestrian Star Rating. Thus, there is a strong wish to increase pedestrian CAE predictive capability for windscreen ...

A sufficient modelling of spot weld behaviour in full car crash simulations is a fundamental item due to the fact that local joint fracture can make a significant contribution to the overall crash performance. The accurate ...

The increasingly demanding and complex requirements in Crash Analysis, call for continuous and innovative software development. BETA CAE Systems in an effort to meet and exceed the requirements of the industry is introducing new ...

Although control parameters of the stamping process are kept constant, remarkable variations in the quality of the stamped parts can be observed during the fabrication of car body parts. This is due to random variations in the ...

Laminated glass is used especially for windscreens and sun-roofs in automotive industry. Pedestrian safety and side impact resistance are in focus of the automotive development. For simulation of head impact on windscreen, side and ...

A disadvantage of aluminium is that it is less formable than steel. One method for overcoming this disadvantage is deep drawing at elevated temperatures. In this way the formability of aluminium sheet metal can be improved ...

In sheet metal forming simulation, Forming Limit Diagram (FLD) has long been used to evaluate sheet metal formability. In conventional method, FLD is obtained by assuming linear strain path (Fig.1); while in real production ...

This talk presents the recent developments in LS-DYNA including LS-PrePost, LS-980, LSTC dummy and barrier development as well as Hybrid LS-DYNA and Implicit update.

This talk introduces into the topic of the new developments on Identification of Material and System Parameters with LS-OPT. It presents current ordinate-based curve matching metric as an example as well as discusses the motivation ...
