Force Distributions Near the Jamming and Glass Transitions



C S. O'Hern, Stephen A. Langer, A J. Liu, S R. Nagel


We measure the distributions of interparticle normal forces P(F) near the glass transition in supercooled liquids and near the jamming transition in foams and compare them to those obtained in recent experiments on static granular packings. We find that the distributions P(F) for glasses, jammed foams, and static granular packings are very similar, showing a plateau or small peak at small forces. We propose that the formation of this peak signals the development of a yield stress in glasses and jammed systems.
