A general analytical and numerical procedure is developed for free and forced vibra tion of thin-walled shells of revolution made of arbitrarily laminated orthotropic elastic material. The equations of motion are derived with the aid of Hamilton's variational principle. A numerical solution is obtained by expanding the variables in Fourier series in the circumferential direction, and using conical finite elements in the meridional direction. Several examples involving different shell geometries are considered, in cluding the effects of fiber orientation and boundary conditions.
