Simulation of cyclic plastic deformation response in SA333 C–Mn steel by a kinematic hardening model

Abstract

Cyclic plasticity deals with non-linear stress–strain response of materials subjected to external repetitive loading. An effort has been made to describe cyclic plastic deformation behavior of the SA333 C–Mn steel by finite element based plasticity model. The model has been developed on the framework using a yield surface together with Armstrong–Frederick type kinematic hardening model. No isotropic hardening is considered and yield stress is assumed to be a constant in the material. Kinematic hardening coefficient and kinematic hardening exponent reduces exponentially with plastic strain in the proposed model. The proposed model has been validated through experimental results.
