Abstract
In this paper, domain integrals due to body forces in the Boundary Element
Method (BEM) for bending of plates resting on elastic foundations are
transformed to equivalent boundary integrals. The Reissner plate bending theory
is used to model the bending behavior of the plate and the Pasternak (two-
parameter) foundation model is used. Unlike common techniques of the
transformation, which are based on the Green second identity, the present
formulation employs the Green first identity which gives smoother and simpler
transformed kernels. The necessary particular solutions are derived. A general
technique for avoiding the appearance of jump terms in the transformed
boundary integrals is presented. Three numerical examples are
