In addition, the coefficients of the obtained models have been calibrated using genetic algorithm optimization method. As the hardening rule in models; bilinear isotropic is combined with Chaboche's nonlinear kinematic hardening rule (three-termed). Plasticity models have been obtained by using the associated flow rule and Hill48 yield criterion in addition to the hardening rules. Experimental stress values have been compared with those obtained from the models. As a result, the most suitable hardening model for monotonic/cyclic loading deformation conditions is presented and the effects of the model parameters on the simulation results are shown.eninfo:eu-repo/semantics/openAccessChaboche kinematic hardening modelbilinear isotropic hardening modelgenetic algorithmAA7075-T6cold forgingArticle3742091210410.17341/gazimmfd.6542002-s2.0-85128710108Q2508754WOS:000767316300026Q4
