Abstract
Non-linear numerical method is applied to solve the viscous-elastic-plastic material impact problem. The finite element simulation agrees with the celebrated European crash safety analysis. The complex material stress distribution in the large deformation has been obtained, when the impact happens. Also the posteriorestimate solver and asymptotic analysis have been used for the sensitive pre-stage deformation before the impact happening. This part of simulation is very interesting for the passive safety in automotive protection devices. It is an important part of the mathematical modelling.
