The objective of this contribution is to investigate the influence of morphological and crystallographic textures on the formability limits of polycrystalline aggregates using the Crystal Plasticity Finite Element Method (CPFEM). The overall behavior of these polycrystalline aggregates is derived from that of the constituent single crystals by the periodic homogenization technique. The single crystal behavior is modeled by a rate-independent finite strain formulation, with the plastic flow rule governed by the classical Schmid law. Ultimately, the prediction of the formability limits is achieved by applying the Rice bifurcation criterion.
