Abstract

The dynamics of granular beds subject to applied stresses are often characterised by repeated cycles of stick-slip motion. The exact structural processes occurring during these repeated cycles are challenging to understand due to the complex multiparticle interactions within the material. Using a computational approach, we reduce the loading imposed on the system to the smallest possible component-a single particle within the bed. This simplified system allows us to isolate the contribution from a single unit of granular material to the overall response of the bed. We use the Discrete Element Method to model a packed, periodic, granular bed responding to the action of a single particle. The ..
