One of the main characteristics of the existing plasticity theories is the lack of a theory and specific equations for them. There are various methods with different results for solution of a plasticity problem. In this paper, two cyclic plasticity models of non-linear (Chaboche) and multilinear (Bessel) kinematic hardening are evaluated based on experimental data for 1% Cr-Mo-V steel alloy. Uniaxial loading on the specimen in seven steps is done by control stress method and using Ansys software. In each step, strains of elastic, plastic and then total have been calculated. The values obtained from simulation compared to experimental results is shown a good agreement on the both results, particularly in non-linear solution.
