Behavior of Multiphase Granular Media: Modeling the Static-to-Viscous Flow Regime

Abstract

In the researched work, assemblages of nearly perfectly round photoelectric disks were subjected to confined compression, the sheared along an interface of varying roughness (very rough or very smooth). Overall, there was excellent comparison between the behavior observed in the physical system and the DEM simulations. Global response as measured by external wall forces, and individual particle kinematics were found to be in excellent agreement. Local contact forces and interactions were modeled generally well, but not as well as the global behavior.
