Abstract: During the pre-design stage, manufacturers in the transportation field need to have access to a simplified simulation and crash optimisation methodology that enables them to quickly ascertain the global behaviour of a structure. The large plastic deformations, localised during the shock, mean that multibody dynamics can be used. They are represented by non-linear spring elements using collapse responses obtained from analytical models in axial compression and pure bending. However, the number and the localisation of these non-linear springs have a direct influence on Central Processing Unit and modelling times and on the quality of results. An automatic method for the localisation and the non-linear response of collapse mechanisms, based on the simultaneous use of analytical results and of a global beam finite element model, is proposed and implemented into a beta version of FE code PAM-CRASH™. To evaluate the robustness of this new tool, an application to a commercial front car part under frontal crash conditions is studied.
