dc.description.abstractanalyzed based on a quadratic Hill48 function and under the application of two plasticity approaches: associated and non-associated flow rule approaches (AFR and NAFR, respectively). The mechanical properties have been modeled, such as the uniaxial flow stresses () and the coefficient of anisotropy r() (or the Lankford parameter). In the identification of anisotropic parameters, the decoupling of the two tensors (strain and stress) under the assumption of non-associated plasticity gives better predictions compared with the experimental. With the purpose of introducing the evolutionary anisotropic path of plastically equivalent characteristics for the uniaxial flow stresses (), the isotropic hardening of mechanical strain hardening function is presented using the following empirical law based on Voce model. Therefore,
