WebJun 15, 2024 · The one-dimensional extended granular crystal consisting of two sub-lattice in this paper is illustrated in Fig. 1 (a). Every sphere in this model is made up of half aluminum (blue) and half stainless steel (gray), whose material parameters are given as Table 1. The mass of each sphere is m = 19.4 × 10 − 3 kg and the radius is R = 9.5 × 10 ... 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.
