....cannot be modeled by using particles of simple spherical geometries. Simulations of ellipses [40] gave already first promising results concerning the behavior of the maximal shear stress [41, 42] Apart from ellipses, super quadrics [43] continuously connected circular segments [44] and polygons [45 49] have been used for a more flexible modeling of the particle geometries and the boundaries. The aim of this paper is to give an insight into the Discrete Element Modeling of spherical and polygonal particles. The physical system (or boundary condition) chosen as an example is the sandpile. First, ....
