Abstract

Force chains figure prominently in shearing motions of granular materials. A simple scaling of the forces involved in the motion of a dry, gravity driven granular shear flow induced by vibrations suggests that this shearing motion reflects a balance between the rate of production and the rate of disruption of granular force chains. The analysis is empirically consistent with the exponential-like profiles of grain displacement, and the strongly nonlinear increase in grain flux with increasing surface slope, observed in experiments
