Abstract
Previous papers developed an approach for estimating the vibration-related broadband acoustic power radiated by a ribbed steel plate in water driven by turbulent boundary layer pressures. This was extended to apply to plates composed of identical ribbed sections joined at infinite impedance supports. In this paper the basic model is modified so that it can be applied to plates composed of dissimilar sections joined at clamped supports. The response is formulated directly in terms of power and the effects of the supports are accounted for by power scattering coefficients, which are calculated through a Wiener-Hopf analysis. Sample calculations are shown to agree with results of other formulations. Only frequencies below bending coincidence are considered.
