Abstract : Modern analytical models and their numerical realizations have become powerful tools in nonlinear crash analysis. Crash simulation has to consider advanced nonlinear constitutive equations and sophisticated formulations of the contact problem. The refinement of discretisation and the treatment of geometrical complex structures requires highly developed hardware like the vector processor. Topics discussed are the material modeling of impact loaded composite structures, the main features of an explicit crash code and the results of two calculations simulating the drop test of a B707-section. Finally the possibilities of a specific interface between a crash code based on the finite element method like ANCS and a program like KRASHB5 are outlined in detail. (JES)
