Simulation of rubber-like materials is usually based on hyperelasticity. If strain-rate dependency has to be considered viscous dampers also have to be taken into account in the rheological model. A disadvantage of such a material ...

Structural bonding with polymer adhesives is becoming more and more accepted in automotive applications in recent years. The development of ductile adhesives, so-called crash-resistant adhesives, aims towards guaranteeing the ...

For crash simulation of the whole car body simplified models for joints, e.g. spotwelds, with limited element dimensions are usually applied to obtain economically acceptable computing times. Since there are no appropriate tools at ...

This paper deals with an advanced model for spotwelds in finite element structures of car bodies under crash loads. The treatment is elasto-plastic, whereas the elastic part as well as the perfectlyplastic part is based on a special ...

Because of weight reduction necessities, high-strength steels are more and more widely used in bodyin-white (BiW) structures in recent years. Concerning the behaviour of such structures during a car crash the joints between ...

The numerical simulation of structural parts made from plastics is becoming increasingly important nowadays. The fact that almost any structural requirement can be combined in a lightweight, durable and cost effective structure is the ...

This talk gives an overview of the current state-of-the-art in sheet metal forming simulation on different examples like Collision Detection, Springback, Producibility Assessment and much more. It concludes with a discussion about ...

This contribution deals with optimization strategies for the crash design. After a short introduction of the mathematical background, the optimization algorithms, and current software systems, special approaches are presented. The ...

The first part of this talk deals with integrative simulation, its motivation, fiber orientation in filling processes, material modelling as well as the influence of fiber orientation tensor. The second part includes simulation ...

About 20 years ago, the first full vehicle crash simulations were performed at Opel. Since then, the rapid development of all simulation tools as well as the tremendously increased computer power have established the capability to ...
