    Forced Vibrations of Thin, Elastic, Rectangular Plates with Edges Elastically Restrained Against Rotation
    (Society of Naval Architects and Marine Engineers, 1977) Enrique A. Susemihl; P.A.A. Laura
    Polynomial coordinate functions and the Galerkin method are used to determine the response of a thin, elastic, rectangular plate with edges elastically restrained against rotation and subjected to sinusoidal excitation. It is shown that when the flexibility coefficients approach infinity (simply supported edge conditions) the calculated results practically coincide with the exact solution in the case of a square plate when four terms of the expansion are used. Dynamic displacement and bending moment amplitudes are tabulated for different length-to-width ratios, flexibility coefficients, and frequency values.
