The vibration of ring-stiffened prolate domes under external water pressure

Ross, C.T.F. / Little, A.P.F. / Chasapides, L. / Banks, J. / Attanasio, D.

The paper presents a theoretical and an experimental investigation into the free vibration of three ring-stiffened prolate domes in air and under external water pressure. The theoretical investigation was via the finite element method where a solid fluid mesh was used to model the water surrounding each dome. Good agreement was found between theory and experiment. Both the theory and the experiment found that, as the external water pressure was increased, the resonant frequencies decreased.
