Prediction of intergranular strains using a modified self-consistent elastoplastic approach

Abstract

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 fee polycrystals. © 2006 WILEY-VCH Verlag GmbH & Co. KGaA.
