A free vibration analysis of internally supported Kirchhoff plates has been presented in the paper. Using the proposed approach, there is no need to introduce Kirchhoff forces at the plate corner and equivalent shear forces at the plate boundary [26], [31], [32], [34]. Two unknown and independent variables have been considered at the boundary element node. The Bettie theorem has been used to derive the boundary integral equation. The collocation version of boundary element method with elements of "constant" type has been presented. The source points are located slightly outside the plate boundary, hence the quasi-diagonal integrals of fundamental functions are non-singular [27], [31], [32], [34].
