Simulation of the kinematic hardening of AISI 316 steel by nonlinear finite element analysis

Abstract

The coupled non-linear transient calculation is performed and explained in order to simulate the kinematic hardening behavior of AISI 316 steel and the Finite Element Method (FEM) is used for presented simulation. The material non-linear models features in Finite Element Analysis (FEA) are explained with special attention in non-linear kinematic hardening material models. For simulating of non-linear kinematic hardening and ratcheting effects of AISI 316 steel the Chaboche constitutive material model is used. The Finite Element Model of rectangular block modeled for material behavior simulation is shown. Definition of constraints and input stresses is explained in detail. The results obtained after six cycles of input stresses give the excellent superposition with theoretical results of other authors. The created diagrams show the ratcheting phenomenon of research material. Therefore, the FEM model developed for non-linear kinematic hardening research is verified and could be used for wide research of different materials under different input loads.
