Non-dilatant double-shearing theory applied to dynamical granular chute flow

Abstract

The non-dilatant double-shearing theory for granular flow is applied to the problem of dynamical chute flow down an inclined slope. Four distinct families of solutions are examined and a number of simple exact solutions are determined which apply to the special case of a granular material with an angle of internal friction equal to ninety degrees. Some of the solutions obtained are illustrated graphically.
