Abstract

This work presents an alternative formulation for plate bending analysis in which the boundary equation of displacements and its derivative in directions normal and tangential to the boundary are used. This formulation considers three nodal values in displacements: w, dw/dn and dw/dt for each boundary node, but according to KirchhofFs hypothesis, only two nodal values are used for the efforts that remains the normal bending moment n\ and the equivalent shear force ¥„. Some examples are presented and the results compared with those of the finite element analysis. 1 INTRODUCTION Many works about the use of the boundary element method for plate bending analysis have been published[l-8]. In all formulations presented in these papers, the integral representations of transversal displacement w and
