A study of free vibration and fatigue for cross-ply closed cylindrical shells using general third shell theory (GTT)‎

الملخص EN

Free vibration solution will be developed for laminated simply supported closed cylindrical shells.

This solution is obtained using General Third Shell Theory (G.T.T.).

Also the critical in-plane fatigue load is studied and the required equilibrium equations are developed, the effects of tension or compression in-plane load on the natural frequencies are discussed also.

The natural frequencies and in-plane fatigue load results are very close to those obtained by other researchers.
