Abstract
The modelling of cohesive, frictional granular materials with a discrete particle moleculardynamics is reviewed. From the structure of the quasi-static granular solid, the fabric,stress, and stiffness tensors are determined, including both normal and tangential forces.The influence of the material properties on the flow behaviour is also reported, includingrelations between the microscopic attractive force and the macroscopic cohesion as well asthe dependence of the macroscopic friction on the microscopic contact friction coefficient.Related to the dynamics, the anisotropy of both structure and stress are exponentiallyapproaching the maximum.
