English Title

Volumetric contact law between convex polyhedral particles

Original Abstract

Simulation of granular material can advantageously performed using Discrete Element Method (DEM). Every grain is treated as ideally rigid body that interacts with surrounding bodies whenever their volumes protrude. There are several algorithms that estimate forces between polyhedrons in contact. The contribution presents another intuitive way that is based on calculation of intersecting volume. Model is used for simulation of railway ballast oedometric test.
