Discrete Element Method (DEM)

The Discrete Element Method is a widely recognize technology for the modelling of geomaterials. The advantages of this method are clearly seen when applied to the simulation of problems characterized for having strong discontinuities. The discrete element model assumes that the materials can be modelled as an assembly of rigid particles interacting among themselves. The overall behaviour of the system is determined by cohesive/frictional contact laws.
