Abstract

The purpose of this chapter is to investigate the mechanical properties of a structural steel under quasi-static and dynamic loads. Specimens of as-received low-carbon mild steel are tested on universal testing machine to study their stress-strain behavior under quasi-static tension (0.001s−1) and compression (−0.001 s−1). Then, the specimens are tested under split Hopkinson pressure bar (SHPB) and modified Hopkinson bar (MHB) to study their material properties under dynamic compressive (−550, −800s−1) and tensile (250, 500s−1) loading, respectively. The material parameters of the existing Johnson-Cook model are determined. Finally, the applicability of the existing Johnson-Cook material model to represent the mechanical behavior of mild steel in plastic zone is examined.
