DEM-aided study of shear band formation in dip-slip faulting through granular soils

A GPU-based two-dimensional discrete element methodology allowing for grain rolling resistance is adopted to study the engineering and fundamental aspects of shear band formation in normal and reverse faulting through an initially dense sand; of course, the paper emphasizes on fundamental aspects. The employed DEM modeling methodology is verified with the experimental results and FEM prediction of the pattern of shear bands developed through a...
