Discrete Element Method (DEM)

It is a numerical approach, which simulates the behavior of a granular assembly (macroscopic mechanical behavior) by modelling discrete particles and their interactions. Therefore, DEM is able to model the behavior of granular materials from a micromechanical point of view by analyzing, for instance, the stress state, chain force, contact orientation and fabric evolution. This method is used in different fields such as pharmaceutical, mining, civil engineering and chemical processes.
