## Abstract A succinct 3D discrete element model, with clumps to resemble the real shapes of granular materials, is developed. The quaternion method is introduced to transform the motion and force of a clump between local and global coordinates. The HertzβMindlin elastic contact force model, incorp
A homogenization strategy for granular materials is presented and applied to a three-dimensional discrete element method (DEM), that uses superellipsoids as particles. Macroscopic quantities are derived from the microscopic quantities resulting from a DEM simulation by averaging over representative
Based on Hill's lemma for classical Cauchy continuum, a version of Hill's lemma for micro-macro homogenization modeling of Cosserat continuum is derived. The derived admissible boundary conditions for the modeling are used to direct the proper prescription of boundary conditions on the representativ
