Hi @BadrynYou can define Chaboche kinematic hardening from the plasticity option in the material data options. If you want to define the a combined isotropic +kinematic hardening model you can use the Chaboche kinematic hardening with any of the isotropic hardening models. If you want a better result for the cyclic loading you should use a chaboche kinematic hardening model with the nonlinear isotropic hardening model (Voce). The calibration method for the chaboche and isotropic nonlinear hardening parameter is shown in these papers. You need a uniaxial cyclic load test. n
