Numerical simulations of the behaviour of cohesionless sand were carried out using a discrete element method. A drained triaxial test of a homogeneous sand specimen under constant lateral pressure was modelled. To simulate the behaviour of sand, a 3D spherical discrete model YADE was used, enhanced by including rolling resistance in order to take into account grain roughness. Numerical results were directly compared with corresponding laboratory tests. The effects of lateral pressure, initial void ratio and micro-parameters on the global behaviour of sand were investigated.
