Strain-hardening is a very significant parameter to evaluate the elastic behavior of a material, especially when numerically simulating the mechanical behavior of the material. In this study, cyclic tensile-compression tests for 316L steel samples were performed to determine the hardening parameters for models such as linear isotropic hardening, linear kinematic hardening, nonlinear isotropic hardening, nonlinear kinematic hardening, and Chaboche model. Thereby, the advantages and disadvantages of each model are assessed. Finally, behavior according to the Chaboche model was selected to propose building an algorithm for the numerical simulation of cyclic tensile-compression experiments. The obtained numerical results are in good agreement with the experimental results.
