Paper Abstract

By including the effect of fluid loading for the thin spherical shell in a proper manner, so- called shell theories can predict the water borne pseudo-Stoneley waves described extensively in the literature. Shell theories give reasonably good results for the motion of a bounded elastic shell by using the assumption that various parts of the shell move together in some reasonable manner. Without proper fluid loading, however, shell theories do not predict the pseudo-Stoneley resonances observed in nature and predicted by exact theory. With proper fluid loading, as well as rotary inertia and translational and rotary kinetic energy terms, a shell theory can exactly predict these water borne resonances. These resonances are predicted by the shell theory and compared with results from exact elastodynamical calculations.
