Abstract

In this paper, domain integrals due to a uniform load that appear in the boundary element formulation for shear deformable plates resting on elastic foundations are transformed to equivalent boundary integrals. The Reissner plate bending model is used to model the plate behaviour and both the one-parameter Winkler and the two-parameter Paster- nak models are employed to model the behaviour of the foundation. Three numerical examples are presented to demonstrate the accuracy of the present formulation. 1. Introduction The Boundary Element Method (BEM) has emerged as a powerful numerical method in engineering applications. The main advantage of the BEM is the boundary only discretisat
