Granular crystals
WebNov 1, 2024 · The granular crystals with medium dense microstructure have widest frequency band gap, and granular crystals with dense microstructures in one-sized and two-sized particles have the same frequency band gap. A qualitative relationship can be obtained that the frequency band gap is negatively related to coordination number and … 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.
