摘要

In order to examine the compatibility of improvement of crashworthiness with weight-saving of automobiles by using high strength steel, a combination analysis of Finite Element Method and Dynamic Mechanical Properties has Been established. The material properties used in this Analysis have been measured by "one bar method" high Velocity tensile tests, which can examine the deformation Behaviour of materials at an actual crash speed range (~55km/h).
