Abstract
The finite element vibration analysis of laminated spherical shell panels with rectangular embedded delamination is carried out based on the third-order shear deformation theory of Sanders. In the finite element formulation for the embedded delamination, the seven degrees of freedom per each node are used with transformations in order to fit the displacement continuity conditions at the delamination region. The numerical results obtained for plates and shells with delaminations are in good agreement with those of other preceding investigations. The new results for composite shell structures in this study mainly show the significant effect of the interactions between the radius-length ratio and other various parameters, for example, embedded delamination size, fiber angles, the number of layer and location of delamination in the layer direction.
