Abstract : Numerical approaches have been extensively developed to predict the mechanical behavior of polycrystalline metals and alloys. In particular, micro-mechanical approaches have been used to take into account the physical mechanisms of deformation at different scales. Self-consistent approaches are common mean-field homogenization methods used to link crystal deformation mechanisms to the overall behavior of heterogeneous materials.
