Taking into account the viscosity of the fluid, the stability of a system of two different fluids being separated horizontally by a thin elastic plate in a gravitational field is studied on the basis of a linear theory. These fluids are incompressible. The plate is infinite in extent and acted on by an in-plane force. The instability considered here arises from the density difference between two fluids and the compression in the plate. In the case of a long wave, the growth rate of the disturbance depends on the density difference, not on the viscosities and the properties of the plate. In the case of a moderate wave length, the viscosities have a stabilizing effect in the sense of decreasing the growth rate, but have no influence on the critical wave number.
