Popis:	Using the wet mode methodology described in Part I of this paper, we examine the harmonic response of an elastic shell in an infinite acoustic medium subjected to an incident pressure wave. Both surface and far field responses are studied utilizing this computational procedure. We investigate the sensitivity of response with respect to changes in frequency of oscillation of the system and geometry of the submerged structure. In addition, we compare the wet modes of the system and in vacuo modes of the structure. The propagation of the surface velocity wet modes to the far field is illustrated. The contribution of the individual modes to the far field pressure and surface velocities as a function of frequency and location is presented.
