| Abstract: | This paper presents a theoretical and an experimental investigation into the free vibration characteristics of thin-walled ring-stiffened circular cylinders and cones. Three ring-stiffened circular cylinders and three ring-stiffened circular cones were machined from a solid mild steel shaft. For each family of vessels, the only variable was the depth of the ring stiffeners. The theoretical investigation was based on the finite element method, and comparison between theory and experiment was found to be good. |
