Abstract

In this study, tensile tests of 304 and 316 austenitic stainless steels (ASS) at various strain rates were performed to investigate the strain rate effect on tensile properties. It is shown that the strain rate effect on stress depends not only on the strain rate but also on the plastic strain level. Accordingly, a modification of the existing Johnson-Cook (J-C) model is proposed to incorporate the interacting effect of plastic strain and strain rate for 304 and 316 ASS. The proposed modified J-C model can reduce the difference from the experimental data at various strain levels, compared to the existing J-C model.
