NONLINEAR-ANALYSIS OF REISSNER PLATES ON AN ELASTIC-FOUNDATION BY THE BEM

The fundamental solutions and the boundary element method for obtaining numerical solutions of nonlinear Reissner plates on an elastic foundation are presented in the paper. The derivation of the fundamental solutions is mainly based on two of Hu's functions and the resolution method of differential operator. An incremental form of the boundary integral equations is suggested to achieve linearization of the original nonlinear equations. The plate may be moderately thick or sandwich plates with (or without) elastic Foundation. Finally, three examples are considered to illustrate the correctness and accuracy of the proposed method.
