The discrete element method (DEM) has only rarely been used to simulate clay, due to difficulties in modelling clay particle shape and capturing the various particle interactions. This paper presents a new approach to simulate clay in three dimensions using DEM, featuring realistic particle shape and a new straightforward interaction law, which is able to reproduce all well-known characteristic platelet interactions. By varying the interactions between the platelets (including both the ‘edges’ and ‘faces’), it is possible to account for a range of environmental conditions. Simple sedimentation and one-dimensional compression tests are presented, which correctly reproduce the expected behaviour, confirming the validity of the model. Particle-scale analysis reveals the influence of the platelet interactions on the bulk behaviour, and it is also shown that platelet aggregation appears to lead to a fractal distribution of aggregated ‘stack’ sizes as a means of space filling.
