We study the shearing flow behavior of granular materials, using a theory based on one proposed by Goodman and Cowin in 1971. Solutions to the equations of motion are presented for the problem of shear flow between two paralled plates. The results show in some cases the narrow, dilatant shear zones observed experimentally and in certain geological processes.
