Rearrangements in flow of foam

ORAL

Abstract

The nonaffine deformation of amorphous solids has attracted considerable attention. Recent simulations and experiments have shown that the non-affine particle rearrangements under an applied stress are localised, and they generate a long-ranged quadrupolar strain field. Here we have investigated the particle rearrangements in flows of soft, viscous spheres near the jamming point. The characteristics of the particle rearrangements are extremely different as we move away from the jamming point.
