“…Yildirim [25] investigated the common effects of the rotary inertia and shear deformation on the first six out-of-plane free vibration frequencies of symmetric cross-ply laminated circular bars with the help of the transfer matrix method on the basis of first-order shear deformation theory. Kovacs [26] presented a new laminate model considering bending and shear deformation of all layers to predict the modal frequencies and damping of a simply supported laminated circular ring segment. Matsunaga [27] investigated the natural frequencies and buckling stresses of laminated composite circular arches subjected to initial axial stress by taking into account the complete effects of transverse shear and normal stresses and rotary inertia.…”

The dynamic stiffness method for studying the vibration characteristics of the laminated composite shallow circular arches is introduced in this article. The exact dynamic stiffness matrix is formulated from the analytical solutions of the governing differential equations of motion of the laminated circular arches, based on second-order shear deformation theory. The application of the present method is illustrated by miscellaneous numerical examples, in which the effects of material orthotropy, the lamination scheme, the curvature ratio, length-to-thickness ratio, and boundary condition upon the natural frequencies of the composite arches are investigated. Compared to those solutions available in the literature, the numerical results demonstrate the accuracy and effectiveness of the present method.

“…The eigenproblem of the plane bending of circular arch-shaped layered beams was investigated by using the "nite element method by Kovacs et al [23]. The "nite element model of the structure has two elements along the face thickness and three elements along the thickness of the core.…”
