Short-term Dynamic Calculation
In contrast to quasi-static FEM simulations, the high accelerations involved in short-term dynamic calculation mean that an impulse is conducted through the component within a very short time. In the case of short-term dynamic calculation, large deformations are typically simulated, in some cases with many interacting components.
High-speed dynamics and highly dynamic events, e.g. vehicle crashes or drop and fall events, are typically characterised by large deformations of the components, components coming into contact with one another or with themselves, and non-linear and expansion rate-dependent material behaviour. For the numerical calculation of such processes or tasks, finite element programs with an explicit integration procedure have established themselves in practice.
Our activities focus on the calculation of drop tests and impact simulations for nuclear containment vessels as well as on forming simulations and crash simulations for components of vehicles and rail vehicles.
