Abstract

We calculate the distribution of interparticle normal forces P ( F ) near the glass and jamming transitions in model supercooled liquids and foams; respectively. P ( F ) develops a peak that appears near the glass or jamming transitions; whose height increases with decreasing temperature; decreasing shear stress and increasing packing density. A similar shape of P ( F ) was observed in experiments on static granular packings. We propose that the appearance of this peak signals the development of a yield stress. The sensitivity of the peak to temperature; shear stress; and density lends credence to the recently proposed generalized jamming phase diagram.
