Avalanching of variously shaped DEM particles

Abstract

Grains in most technically relevant granular materials are non-convex, while in discreteelement-simulations, convex particle shapes dominate. While differences in the physical behavior can be expected, the actual observables where these effects manifest are far from clear. In this research, we investigate how in a rotating two-dimensional drum, the physical behavior for rounded, irregular convex as well as non-convex shapes differs.
