Sparse locally-jammed disk packings

WebA jammed packing is one in which the particle positions are fixed by the impenetrability constraints and boundary conditions [3, 4]. In particular, a packing is locally jammed if ... 1 shows the polytope P∆R for a locally jammed disk, for both an isostatic and a hyperstatic case. In this work, we focus on collectively jammed packings, since ... WebThe results show not only that the packing undergoes a structural change upon jamming, but also that bidisperse packings exhibit local HCP and FCC structures also found in …
