Isotropic and Kinematic Hardening Plasticity Model

Question - Can isotropic and kinematic hardening plastic model be used simultaneously?

Answer - Currently, the only kinematic hardening model that can be used in conjunction with an isotropic hardening model is the Chaboche model, which is nonlinear. However, it is possible to simplify the Chaboche model to a bilinear kinematic model by choosing n = 1, where n is the number of material models, and gamma_1 = 0, where gamma_1 is the rate of decrease of the hardening modulus.
