Crash Simulations

Crash simulations are performed in order to assess the crash safety of various components and validate the applied material models; the results are compared to those of component trials. The commercial PAM-CRASH, LS-DYNA and ABAQUS crash codes are often combined with user material models. In order to account for the effects of manufacturing processes on crash behavior, one can, for example, transfer pre-stretching and previous damage from deep drawing simulations or porosity from casting simulations into crash models.
