Abstract
This paper provides a rigorous solution of a free rectangular plate on the V.Z.Vlazov two-parameter elastic foundation by the method of superposition[1]. In this paper we derive basic solutions under the various boundary conditions. To superpose these basic solutions the most generally rigorous solution of a free rectangular plate on the two-parameter elastic foundation can be obtained. The solution strictly satisfies the differential equation of a plate on the two-parameter elastic model foundation, the boundary conditions of the free edges and the free corner conditions. Some numerical examples are presented. The calculated results show that when the plane dimension of plate is given and the ratio between the layer depth and the plate thick is equal to 15, the two-parameter elastic model is near the Winkler's. It shows that the Winkler model can be applied to the thinner layer.
