Behavior of 316L Stainless Steel under Static and Dynamic Loading Conditions

Abstract

In the present study, 316L stainless steel was characterized for microstructure and mechanical behavior under static and dynamic loading conditions. It showed a high ratio of tensile strength to yield strength with good ductility. Experiments on strain controlled tests, performed at 0.25 Hz frequency, resulted in reduction of fatigue life with increasing total strain amplitude. At higher strain amplitudes, secondary cyclic hardening was noticed. In contrast, cyclic hardening was observed for initial few cycles followed by softening up to failure at lower strain amplitudes. © 2022 University of Kuwait. All rights reserved.
