WebJan 1, 2015 · Abstract. We simulate the dynamics of impacts on 1D, 2D and 3D arrays of metallic spheres in order to design novel granular protection systems. The dynamics of these highly organized systems of spheres, commonly called granular crystals, are governed by the contact law that describes how each particle interacts with the others. http://minsocam.org/MSA/collectors_corner/id/mineral_id_keyi8.htm
