Discrete Element Method (DEM) is a numerical scheme pioneered by Cundall and Strack (1979) for simulating the behavior of systems of discrete interacting bodies. This numerical method allows finite displacements and rotation of discrete bodies where complete loss of contact and formation of new contacts takes place as the calculation progresses.
