Vehicle safety is gaining an always more significant role for the marketing of a new vehicle. Consumer tests serve to reproduce realistic accident scenarios. A majority of the accidents bearing a high risk of injury and fatal ...

Vehicle collisions can be considered as a highly dynamic deformation process, where structural steel deforms under different strain rates. Therefore, an appropriate material model, which takes rate affects into account, has to be ...

This talk introduces the Barrier Development Programme of Arup

The offset deformable barrier consists mainly of honeycomb blocks with highly anisotropic behaviour. These parts are made from several layers with aluminium foil that is glued and stretched to form the honeycomb structure. Simple ...

Windscreens from laminated safety glass (glass/PVB interlayer/glass) are widely used in automotive structures and have an important contribution to the stiffness of the vehicle. The stiffness of the laminated safety glass is ...

Zur Bewertung des Werkstoffverhaltens unter Lastbedingungen des Crashs wurden und werden in großem Umfang Fallturmversuche an verschiedenen Crashprobekörpern durchgeführt. Die Überführung dieser Versuchsergebnisse in eine skalare, ...

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 ...
