A multi-scale model that allows to predict the evolution of the crystallographic texture and the corresponding plastic anisotropy during a metal forming process is assessed for the cup drawing of a low-carbon steel. Anisotropic explicit finite-element simulations of the forming process are coupled with micromechanical models. Plastic anisotropy is described by means of Facet expressions for plastic potentials in strain rate space using the full constraints Taylor theory. Textures predicted by the ALAMEL model are found to be in better agreement with experiments than those obtained with the full constraints Taylor theory.
