An analytical tool for buckling and vibration analysis of laminated shallow curved panels is presented. The equations in terms of transverse displacement and Airy stress function are derived via the Hu -Washizu mixed formulation and solved by the Ritz method, using the eigenfunctions of an isotropic beam. The effect of the prebuckling state and out-of-plane natural boundary conditions is examined. The approximate reduced bending stiffness method is evaluated for cross-ply and angle-ply laminates. © 1992.
