Demand for increased impact safety as well as weight reduction of automobiles has increased the use of high-strength steel sheets. The impact energy absorbing capacity of high-strength steel sheets up to 590 MPa was investigated by the finite element method (FEM) analyses in combination with tensile tests at speeds comparable to those of automobile collisions. The FEM analyses show that high dynamic strength and high work hardenability that improves the stability of the buckling process are advantageous in enhancing the impact energy absorbing capacity of automobile parts. TRIP (transformation-induced plasticity) and DP (dual-phase) steels are superior in these properties and suitable for impact energy absorbing components.
