Abstract

Galerkin's procedure and the modified energy expression of Banerjee are used to obtain the central deflection of circular plates with linearly varying thicknesses, resting on a linear as well as a nonlinear elastic foundation. A new series formula for the deflection has been considered. The accuracy of the method has been tested for clamped plates with movable and immovable ends under uniform static patch loading. Graphical results are drawn for the central deflection for different end conditions, different plate thicknesses and different foundation properties. Comparison of the results are made with other known results and shows a good agreement in most tested cases.

Nonlinear Analysis of Circular Plates on Nonlinear Foundation
