Dem of relative density
WebIn contrast, the discrete element method (DEM) is a good tool to simulate granular materials because of their discontinuous and heterogeneous natures [ 19 ]. In practice, the DEM has been widely used to reproduce the laboratory tests on granular materials (e.g., soil, sand, and RFM) [ 20 – 22 ].
