The identification of an appropriate design for engineering structures and processes is a development task over a long period of time. Finally, the developed design should be primarily reliable. Focusing on reliability purposes just ...

Due to environmental aspects in automotive industry weight reduction of body parts is one of the main challenges. Increase of safety and comfort requirements accompanied by decrease of weight leads to the necessity of complex ...

Roller hemming is an operation used in the construction of vehicle body parts and follows on from deep drawing, trimming and folding the flange to produce a metal-formed joint between the outer skin part and the inner part of vehicle ...

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 ...

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 ...

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 ...

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 ...

This paper presents the extension and validation of the damage model GISSMO (Generalized Incremental Stress State dependant damage MOdel). The damage model is extended for 3D usage by utilization of Lode angle parameter. The fracture ...
