The term crash simulation originally comes from the automotive sector and has the goal of reducing the crash behavior of expensive prototypes in testing with the aid of virtual crash models
and at the same time to meet the ever-increasing demands on vehicle safety.
The crash behavior of new vehicle models is examined and optimized in the computer at an early stage.
Optimal crash behavior and weight reduction are often opposing goals. Crash simulations can be used here to find compromises between the lightest possible design and a safe passenger cell. The number of costly crash tests is reduced, which also shortens development times.
In our crash simulations, we place particular emphasis on the connection technology of the individual components, as well as the creation of the necessary material cards, even for exotic materials such as foams, fiber composites, wood, plastics.
Crash simulations on automobiles have become more of a standard investigation and are no longer considered "Rocket Science".
In addition to vehicle components or complete vehicles, we also investigate the crash behavior of motor homes with interiors as well as the behavior of aircraft seats in the VIP area during hard landings.
We are increasingly focusing on marginal niches, e.g.
etc. which can be simulated with the same calculation methods, but which require specific know-how.
For this purpose, we also require strain-rate-dependent material parameters in unusual strain rate ranges, which we can determine together with partners even for very high strain rates.
Together with our partner Digimat, we can also describe complex materials and composites computationally.
Currently, we are working on the interaction of real human models from computer scans against external impacts.

The primary focus of such investigations is safety. Are your safety precautions suitable to protect people from flying parts (containment) or to protect people from injuries in case of an impact if possible (vehicle crash, safety cell). In second place is the resulting damage, which should be minimized (packaging, transport).
