| Abstract | ||
| In this article, stress analysis of laminated composite and sandwich cylindrical shells is presented using equivalent single layer higher-order shell theories. A theoretical unification of the several shell theories is presented using a generalized shell theory. A theory is independent of the choice of shape function associated with the transverse shear stress. The present theory satisfies traction free conditions on the top and bottom surfaces of the shell. The principle of virtual work is employed to formulate governing equations and boundary conditions. Closed-formed analytical solutions are obtained using the Navier\'s solution technique. Numerical results are obtained for simply supported laminated composite and sandwich cylindrical shells. | ||
