In order to simultaneously satisfy the conflicting requirements of weight reduction and improved crash-worthiness for automotive bodies, the application of high strength steel sheets is effective. For the purpose of making it possible to select material characteristics of high strength steel sheets which produce formed parts with stable shapes or to select shapes for formed parts which have suitable material characteristics for high strength steel sheets, the advance evaluation of impact energy absorbing capabilities as body parts and of shape fixabilities at press forming has been investigated by means of FEM simulation. The results show that it is possible to evaluate the impact energy absorbing capabilities as automotive body parts taking the dynamic deformation characteristic of steel sheets into consideration. The material characteristics, which are mainly governing the shape fixabilities, change from yielding strength to tensile strength as the bending radius decreases.
