Implementation of an evolving anisotropic behaviour for the hexagonal closed packed materials
Abstract : In this work an anisotropic model belonging to the Barlat's criterion family is implemented for the metal sheet processes, and described into two parts: the kinematics and mechanical considerations. A return mapping algorithm is implemented to solve the stress increment. First order development and numerical differentiation must be used, due to the complexity of the yield criterion derivative.
