A novel approach is adopted to describe the plasticity evolution and determine the active deformation systems with an elastoplastic self‐consistent approach. A modified formulation of the crystal behaviour is proposed. This model is tested by simulating the development of intergranular strains during uniaxial tension of MONEL‐400 as well as commercial purity aluminium. Neutron diffraction measurements of the elastic strains are used as a reference. The results show the relevance of the model for fcc polycrystals. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
