✦ Synopsis

The natural frequencies for the axisymmetric vibration of closed symmetrically layercd or thotropic spherical shells and closed non-symmetric cross-ply spherical shells are obtained by using a theory proposed earlier by the authors, which includes the effect of shear deformation and rotatory inertia. The axisymmetric vibration consists of pure torsional motion and flexural motion, which are uncoupled. The solutions for the flexural motion are obtained by a weighted residual method and exact solutions are obtained for the torsional motion. The results obtained with the present equations are compared with those of classical equations.
