Modelling of railway ballast response using Discrete Element Method with polyhedral shape of grains is presented. The convex polyhedrons are generated pseudorandomly via Voronoi tessellation. Inter-particle contact is based on calculation of intersecting (polyhedral) volume. Large oedometric test is simulated using this model and results are compared to an experimental data from literature.
