What is the Discrete Element Method (DEM)?

This eBook describes the theoretical background behind the Discrete Element Method (DEM) - a particle-scale numerical method for modeling the bulk behavior of granular materials and many geomaterials such as coal, ores, soil, rocks, aggregates, pellets, tablets and powders. The following topics are covered: - Modeling Approaches - DEM Background - Particle Motion Calculations - Time Steps - Interaction Models - Contact Detection - Particle Shapes - Material Calibration - Geometries in DEM - Coupling DEM with other CAE tools
