Closed form analytical solutions are given for the point force and point moment mobilities at the free edge of a semi-infinite plate. Previously, these solutions have been known only in terms of unsolved integrals. The solutions give mobility as functions of Poisson’s ratio times the characteristic mobility. The edge-excited plate therefore can be added to the relatively small number of structures for which exact solutions are available. The value of such solutions lies in allowing computer simulations, and testing for approximate methods.

A possible interaction between the acoustic waves, which are generated from a water-entry body (moving source), and a submerged elastic shell is investigated theoretically within the scope of linear theory. The incident wave is defined from the ballisticwavemodel. The transient interaction is solved through extension of a method formulated for the excitation from a stationary source in an infinite domain. Numerical examples for the incident wave forms and corresponding shell responses are given to illustrate the effect of a moving source on the structure response.
