Reorganization of a 2D disordered granular medium due to a small local cyclic perturbation
E. Kolb, C. Goldenberg, S. Inagaki +1
We measure experimentally the rearrangements due to a small localized cyclic displacement applied to a packing of rigid grains under gravity in a 2D geometry. We analyze the evolut…

Reorganization of a dense granular assembly: the `unjamming response function'
E. Kolb, J. Cviklinski, J. Lanuza +2
We investigate the mechanical properties of a static dense granular assembly in response to a local forcing. To this end, a small cyclic displacement is applied on a grain in the b…
