Stickslips with Granular Particles

ORAL

Abstract

We study the emergence of stick-slip instabilities with densely packed granular particles that are sheared continuously. Such behavior occurs in a route of transition between suspension dynamics and plastic flows, as a result of changing the shear rate. Counterpart experiments are designed in order to identify the origin of stick-slips between two particles. We discuss the possible connection between the system-sized avalanches and the local instabilities.
