From concept to engineering, and from design to test and manufacturing, the automotive industry relies on powerful virtual development solutions. CFD and crash simulations are performed in an effort to secure quality and accelerate ...

One - step simulation with keyword *CONTROL_FORMING_ONESTEP has been widely in use in crash and safety for forming stress and strain initialization. It has also being used for initial estimating of blank size in ...

In the last decades, the use of polymeric materials in the automotive industry has increased dramatically. This demand is linked to the good ratio between cost, density and mechanical properties for this class of ...

Complex material models are much more used nowadays. The reasons are the increasing usage of plastics in high security relevance automotive and the resulting demand for virtual modeling including damage and failure. ...

In recent years the light weight construction has become more and more important due to the rising demand of energy savings. Coming along with that reason plastics substitute other materials and they are also carrying the applied ...

The airbag door system is one of the most delicate aspects in the design phase of a car instrument panel: seamless systems are increasingly used, which combine styling criteria with good functional ...

In this contribution, an elasto-plastic model has been proposed based on a yield surface dependent on the third invariant of deviatoric stress tensor, in order to describe the mechanical behavior of wide range of ductile materials. ...

As alluded in the first part of the present contribution, strain rate effects are quite relevant during a high speed crash event. If one intends to accurately predict failure under such conditions, it is important to properly ...

The dynamic behavior of materials plays a major role in crashworthiness. During a high speed crash event, the material undergoes different strain rates that may affect its constitutive behavior. For instance, in the first milliseconds ...
