Reorganization of a granular medium around a localized transformation
Abstract eng: Rearrangements of a two dimensional granular packing undergoing a local transformation are studied. We accurately track each particle of a model granular packing made of inert disks and of an intruder pulled out at constant speed. Long term displacements are similar to displacements for 2D quasi-static silos. Short term reorganizations are more heterogeneous in space and time. Structural evolutions exhibit a unique mechanism of rearrangement in terms of density variations whatever events amplitudes.
