Simulation of auto body structures has been carried out by an elasto-plastic explicit finite element method with shell elements and the plastic-predictor elastic-corrector (PPEC) scheme in stress integration. A dynamic constitutive model of sheet metal is constructed with the tension split Hopkinson bar experiment and used in simulation. Simulation results demonstrate remarkable difference in deformed shapes and the impact energy absorption between the static model and the dynamic model.
