DEM

The Discrete Element Method (DEM) is usually applied to predict the behavior of different types of granular media during mixing processes, storage and discharge or transportation on belts. Friction coefficients as well as spring and damper constants can be defined in normal and tangential direction. A continuum-mechanical description can be obtained with the introduction of “bonds” between the particles. Herein, the required mechanical behavior of the bonds is automatically computed by LS-DYNA using the parameters given in the material card.

This LS-DYNA example shows the injection of a granular material into a funnel using the discrete element method (DEM).  …more
