| Abstract: | An analytical method is developed to determine the steady-state dynamic response of submerged densely ring-stiffened circular cylindrical shells under the excitation of harmonic forces and moments. Flugge' s thin shell theory is utilized in the formulation of equations of motion and the effect of fluid-structure coupling has been taken into account. The effect of the stiffeners is handled as orthogonally anisotropic and taken as evenly spread over the shells. Analytical solutions are obtained through wet modal expansion. Numerical results are presented for a given ring-stiffened cylindrical shell with some meaningful conclusions. |
