In this paper, the vibratory characteristics of a rectangular plate in contact with water on one side are studied. The elastic plate is considered to be a part of a vertical rectangular rigid wall in contact with water, the edges of which are elastically restrained and parallel to those of the rigid

โฆ Synopsis
This paper deals with the free vibrations of infinite elastic plates in the presence of water. Although this is a textbook problem, which has been studied a long time ago, no exact solution in the framework of linear theory seems to have been given so far. A very simple exact solution given in the paper permits the computation of "added virtual mass factors". It is found that the results not only differ quantitatively but also qualitatively in an important manner from the known approximate textbook solution: no threshold wavenumber for acoustic short circuit is found with the exact solution.

This paper describes an approach to calculate the radiation efficiency of infinite plates subject to a point load for any frequency. The results obtained by this approach are valid for the radiation efficiency of point-driven finite plates in water with real world material properties for frequencies
The problem of bending vibration of a polar-orthotropic non-homogeneous elastic plate on an elastic foundation is considered, and the invariance of the problem-equation under an inversion transformation with respect to a circle is proved. As a corollary, the optimization problem (the ''best'' positi
