Abstract

We do molecular dynamics of shear-driven jamming of elastic particles with contact-only interaction. Our present work has two main goals: 1. To demonstrate convincingly that the viscosity exponent, contrary to the prevailing picture, is different in three dimensions than in two dimensions. 2. To explore all kinds of phenomena for shear-driven jamming of ellipsoidal (instead of spherical) particles. This includes characterizing the jamming transition and exploring consequences of the "quartic" modes that are present in packings of jammed particles, and also should affect shear-driven jamming in the limit of small particle overlaps.
