Free Vibrations of Anisotropic Laminated Doubly Curved Shells
Free vibration characteristics of laminated composite shells are presented using an isoparametric doubly curved quadrilateral shear flexible element. First-order shear deformation theory is accounted for using an extension of Sanders' shell theory. The effects of in-plane inertia and rotary inertia are considered in the formulation of the mass matrix. Numerical results are presented for the doubly curved composite shells to study the influence of various important aspects of the problem such as change in shell geometry, orientation of layers, material parameters, and boundary conditions on the frequencies. Results for plates and cylindrical shells are also presented as special cases and are compared with those available in the literature.
