摘要：
We have developed a combined finite element (FE) - elastoplastic self-consistent polycrystalline plasticity (EPSC) model. The FE code describes the macroscale geometric relationship. The EPSC model describes the response of each individual element in the FE code, incorporating a full description of plasticity at the crystallite level. A simple bending experiment has been performed on stainless steel, and neutron diffraction strain scanning used to determine the variation of intergranular strains as a function of position in the bent component. The model predictions of spatial variations in hkl strain have been compared with the experimentally observed variations.
