Abstract : The asymptotic high frequency response of a point-excited, submerged thin cylindrical shell is evolved. The results are compared with the corresponding asymptotic responses of thin plates and spherical shells. A ray theory for the structural responses of both submerged and in-vacuo thin structures subject to point-force excitation is proposed and is shown to agree with available known solutions. (Author)
