The effect of anisotropy on the natural frequencies and modes shapes of laminated composite shells of revolution is studied by a semi-analytical solution method which exploits the combination of the numerical integration technique, and a modified frequency trial method. The governing shell of revolution equations comprise the full anisotropic form of the constitutive relations, including first order transverse shear deformation, and all components of translatory and rotary inertia. To study the coupled effect of anisotropy, geometry and boundary conditions on the vibration characteristics of anisotropic shells of revolution, numerical results are obtained for different shell geometries with different boundary conditions. Emphasis is placed on the effect of fibre orientation angle, stacking sequence, and coupling stiffness coefficients on the natural frequencies and modes shapes of anisotropic shells of revolution.
