THE DISCRETE ELEMENT METHOD Definition: a numerical method belongs to DEM if it consists of separate, finite-sized elements and their contacts its elements have independent degrees of frredom, with large displs contact separation and sliding considered; new contacts can be born Main steps: define the elements (geometry); You will not need to purchase a textbook or other materials. At nor­mal scales a gran­u­lar flow is made up of mil­lions of small par­ti­cles (grains of sand, for in­stance) each of which is sub­ject to the laws of sol­id me­chan­ics. Primary fields of applications are strength of materials (deformation and stress analysis) and dynamics and vibrations. Corresponding Author.
