Abstract ： A dynamical model is presented for a thin layer of granular materials similar to that for shallow viscous fluid. We have obtained analytically the expressions for the “thermal expansion”, dispersion relation, and dependence of instability onset on driving frequency and viscosity, which are in agreement with experiments. The numerical calculation for the nonlinear problem reproduces the experimental phenomena for a one-dimensional system.
