Studies on the Mechanics of Rapidly Flowing Granular-Fluid Materials.

Abstract

This work addresses the subset of flows of granular materials known as rapidly flowing, granular-fluid materials. Experiments were conducted in an annular, parallel plate shear cell with two primary goals in mind. The first was to investigate the existence of an internal boundary above which the material deformed rapidly, but below which the material remained rigidly locked in place. The second goal was to examine the constitutive behavior of rapidly flowing granular-fluid materials bounded by parallel, roughened plates. The constitutive theories of McTigue (1979) and Jenkins and Savage (1983) are applied to study the steady, rapid flow of a semi-infinite granular bed under the influence of gravity and traction applied to its surface. Analytic solutions based upon McTigue's theory and numerical solutions based upon Jenkins and Savage's theory both suggest that there is a finite thickness of motion in the bed.
