Kinematics of Shear Banding in 3D Plane Strain DEM
Shear banding is generally viewed as a form of instability that occurs when the observed states of a system permit a bifurcation in the solution path to two (or more) solutions. The mechanics of shear bands have been studied extensively both experimentally and analytically, yet mostly in a qualitative manner and in two-dimensions. The evolution of the micro-deformation mechanism leading to the development of shear bands is still not well understood and has important implications in three-dimensional analysis. Presented herein is a promising method of modeling the micromechanics of the shear band phenomenon in plane strain using parallelized discrete element method (DEM). The preliminary results show the DEM’s capability of responding correctly to different loading conditions giving an accurate depiction of the behavior of real soil. The preliminary results from the DEM simulations are presented and discussed.
