| Abstract: | By synthetically considering grain boundary and its influence zone, the microme chanical model of polycrystal is established for considering the influence of grain boundary. By using crystal plastic theory and finite deformation finite element method, numerical simulation is carried out for the model. Numerical results display the mecroscopic characteristic of deformation fields of grains. Calculated results are in qualitatively agree with experimental results. |
