A boundary integral equation formulation for the general solution of plate bending problems is presented. plate bending theory, a set of Bearing on Kirchoff's thin, elastic simple integral equations on the plate boundary is developed using the and Betti. Included herein are classical reciprocal theorem by Maxwell the concepts of a "decoy" domain whose solution at any arbitrary point is completely determinable; and a "virtual" plate that incorporates the boundary conditions of the real plate and has its forces distributed around the boundary of the region only. Hence , no double integral term is required to account for the domain loading. The solution of the basic integral equations yield the boundary unknowns of the plate. Thereafter, the solution can be extended to any point inside the domain by simply including only the point of interest in the boundary integral equation.
