Percolations induced by quasistatic shear in athermal systems with weak attraction

ORAL

Abstract

When quasistatically shearing athermal particulate systems with weak attraction, we observe both connectivity percolation and solidlike transitions over a wide range of packing fractions below the jamming transition point. It is already known that without shear connectivity percolation for the same system occur at specific packing fraction, φcp. It is interesting that driven by shear the system undergoes percolation transition even far below φcp. We find that φcp and another specific packing fraction approximately separate the whole packing fraction regimes into three parts, in which the connectivity percolation exhibits apparent differences. Combining the static structure factor, we come up with a novel phase diagram with percolation transitions, and regimes of phase separation, gelation, shear jamming, and jamming.
