摘要：
In this paper, we carried out the true triaxial test simulation under plane strain condition with three dimensional DEM analyses (3D DEM) to study behavior and development of shear band. The maximum mobilized internal friction angle corresponds to the shape factor, FU, on a linear relationship, and the inclination of the linear relationship seems to become larger with the microscopic angularity of the grain. The thickness of the shear band increased with the grain size. Also the grain shape affects on the relationship of residual stress ratio to relative shear displacement along the shear band.
