NUMERICAL SIMULATION AND OPTIMIZATION OF UNIAXIAL TIME-INDEPENDENT CYCLIC PLASTICITY
The uniaxial cyclic plasticity of IN100 material is simulated and optimized by iSIGHT software with constitutive model which is adopted according to the characteristics of the time-independent fatigue test in this paper. The concept of yield surface and the decomposition of hardening into kinematic and isotropic hardening are used in the model. The material parameters of the constitutive model are analyzed and identified through the optimization. The selected model and parameters can present accurate simulations for the corresponding experimental data.
