Granular crystals
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. WebSep 21, 2012 · Schematic of extended granular crystal analyzed in the present study. Larger sized granules represent spheres (radius, R) while smaller ones are cylinders (radius, r). Wave propagation studies are performed on an extended set of this packing by giving a symmetric disturbance, setting initial velocities on four spherical granules as …
