A polycrystalline plasticity model, which incorporates the contribution ofdeformation twinning, is proposed. For this purpose, each material point istreated as a composite material consisting of a parent constituent and multipletwin variants. In the constitutive equations, the twin volume fractions andtheir spatial gradients are treated as external state variables to account forthe contribution of twin boundaries to free energy. The set of constitutiverelations is implemented in a spectral solver, which allows solving thedifferential equations resulting from equilibrium and compatibility conditions.The proposed model is then used to investigate the behavior of a AZ31 magnesiumalloy. For the investigated loading conditions, the mechanical behavior iscontrolled by the joint contribution of basal slip and tensile twinning. Also,according to the numerical results, the development of crystallographictexture, morphological texture and internal stresses is consistent with theexperimental observations of the literature.
