Modelling railway ballast with accurate grain shape representation using rigid blocks in PFC3D

The webinar introduces a workflow to digitize and simplify ballast stones, grain shape quantification systems, different contact treatment and breakage models and their application in PFC3D to simulate large scale shear box tests.

The shape of the individual stones in railway ballast has a significant impact on the mechanical behaviour of the track bed. Convex rigid blocks allow to model grains with good accuracy while maintaining reasonable computational demand.
