dc.description.abstractA novel combined hardening model integrating bilinear isotropic and nonlinear kinematic hardening rules is proposed to simulate the cold wire drawing process of AA7075-T6. The plasticity model is formulated using Hill48 yield criterion, the proposed hardening rule, and the associative flow rule. Firstly, the experiments of monotonic tensile and low cycle fatigue tests are carried out and true stress-true plastic strain data are obtained. The parameters of the hardening rules and anisotropy coefficients for yield criterion are determined using the obtained test data. An inverse analysis is performed to calibrate the parameters using optimization and the finite element-based wire drawing simulation. The hardening curves of a combined model, bilinear isotropic hardening rule, and Chaboche's nonlinear kinematic hardening rule are compared as their performance metric. Validation is achieved through experimental results, and the optimum and calibrated parameters for wire drawing of AA7075-T6 are proposed. The results offer an insight into the hardening model, its parameters, and their sensitivity for the wire drawing simulation. It is concluded that the prediction of the combined model is more accurate than those of bilinear isotropic and Chaboche's nonlinear kinematic hardening rules. The drawing force requirement and material flow path are also determined.
