Experimental and numerical simulation of carbon manganese steel for cyclic plastic behaviour

Abstract

The paper deals with finite element modeling of saturated low cycle fatigue and the cyclic hardening phenomena of the materials Sa333 grade 6 carbon steel and SS316 stainless steel. Von Mises’ yield function and Chaboche’s kinematic hardening rules have been used. The recall terms of Chaboche’s kinematic hardening rule is calibrated with a memory function. The evolution law of the memory function is determined from experimental observations. The material constants are identified and derived from experimental results. The FE simulated results are compared with the experimental results from virgin state to saturation state of the materials.
