Abstract:

This research paper deals with the influence of Winkler and Pasternak elastic foundations and functionally graded material on the free vibration characteristics of a cylindrical shells submerged in fluid. Love’s thin shell theory has been employed for strain- and curvature displacement relationship. Wave propagation approach is used to solve shell dynamics equations. Influence of fluid, functionally graded material and Winkler as well as Pasternak elastic foundations are studied on the natural frequencies of submerged cylindrical shells. Results obtained are confirmed by the comparisons from the existing ones in literature.
