Rigidity phase transition in granular packings. Academic Article uri icon


  • We numerically model two-dimensional systems of granular aggregates confined between two rough walls and demonstrate that at a critical grain volume fraction nu(c) an abrupt rigidity transition occurs. The transition has first-order characteristics, although the elastic constants undergo a second-order transition. Densely packed grains, with a volume fraction nu>nu(c), display an elastic-plastic rheology. Loose packings, with nu
