英文摘要The discrete element method (DEM) is used to analyze complex practical granular systems; however, the representation of real shapes is an important consideration because behavior of non-spherical particles is unlike that of spherical particles both individually and collectively. In this study, we use non-uniform rational basis-splines (NURBS) to describe the shapes of non-spherical particles and introduce a contact detection scheme based on quadratic convergence, to simulate the behaviors of elliptical particles. The simulation results are compared with those based on polygons, in terms of the shape description and contact treatment, to demonstrate the high accuracy and efficiency of NURBS-based DEM.
