DEM simulation of ballast oedometric test
Original language description
The granular nature of the railway ballast in connection with fast dynamic loading makes it an ideal application of the Discrete Element Method (DEM). The contribution employs DEM to simulate the ballast behavior in large oedometric test. Ballast grains are represented by convex polyhedral particles with shape randomly generated via Voronoi tessellation. A novel algorithm to compute repulsive contact force based on intersecting volume of polyhedrons is presented. Crushing of grains is included via splitting the particles into smaller polyhedrons when some stress-based criterion is fulfilled.
