In the homogeneous case, the plate displacement is expressed by a Green formula. which involves the infinite fluid-loaded plate kernel. When stiffeners are present. they are accounted for by line forces. The densities of which are unknown functions. The boundary conditions and the continuity conditions on the stiffeners lead to a system of integral equations. The solution of which exists and is unique. This system is solved numerically by a collocation technique, in which the unknown functions are approximated by C1-elements. Examples of directivity patterns of rectangular plates are given.
