摘要：

This paper presents the experimental methodology used by R&D EMEA - Global Materials Labs Department to test metals at high strain rate of 500 s(-1). The implementation of dynamic results in commercial FEM Software LS - DYNA for crash simulation are presented. The effects of the strain rate on the tensile properties of metals, used in automotive field, are evaluated using results obtained from a direct tension split Hopkinson bar, built in collaboration with the University of Applied Sciences of Southern Switzerland DynaMat Lab. Finally the complete mechanical characterization of the Magnesium alloy AZ31B is presented, from static up to dynamic tests, showing its applications in FCA (Fiat Chrysler Automobiles), problems and future developments.
