Summary
This paper presents a study of the micromechanical response of granular materials in the Direct Shear Test (DST) using DEM (Discrete Element Method). Parametric studies were conducted to investigate the effects of specimen length and height (in relation to the particle size) on the bulk granular material shear strength and shear banding behavior in the DST. A mesh-free strain calculation method previously developed by the authors was used to capture and visualize the evolution of strain localization and failure inside the direct shear box.
