摘要：

The distributions of strain and resolved shear stress in a copper bicrystal with the grain boundary perpendicular to the tensile axis were analyzed by a three-dimensional anisotropic finite element method. The differences of strain and resolved shear stress between two component crystals, between the region close to the grain boundary and the region far from the grain boundary, and between the free surface and the interior region, were studied. This paper presents some general trends about the changes of strain and resolved shear stress near the grain boundary in the bicrystal with a grain boundary perpendicular to the tensile axis.
