Calculating rotational motion in discrete element modelling of arbitrary shaped model objects

摘要

Application of the discrete element method (DEM) to real scale engineering problems involving three-dimensional modelling of large, non-spherical particles must consider the inertia tensor and temporal change in the orientation of the particles when calculating the rotational motion. This factor has commonly been neglected in discrete element modelling although it will significantly influence the dynamic behaviour of non-spherical particles.
