Natural frequencies of clamped-free circular cylindrical shells

Abstract Some experimental studies of the circumferential mode vibration characteristics of clamped-free circular cylindrical shells are reported and the results compared with some available theoretical predictions. Good agreement has been obtained for the natural frequencies for configurations typical of unstiffened steel stacks. Measurements of structural damping for aluminium and steel shells have shown that this is not a function of mode shape and is nearly the same for both materials.
