A study of buckling and vibration of laminated shallow curved panels

Abstract

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.
