Abstract

This paper introduces boundary integral equations for bending moments and shear forces for thick Reissner plates on two parameter elastic foundation. The reduction of domain loading integrals to boundary integrals or simple terms, is demonstrated in those integral equations, for cases with generalized loading, which include concentrated loading, and line loading acting on arbitrary curves defined on the plate surface. Several case studies with different boundary and loading conditions, have been analysed and results were compared with corresponding analytical solutions. It has been shown that the new formulations lead to very accurate solutions for bending moments and shear forces at different points inside the plate.
