An optimization procedure is proposed for design of fibrous composite plates having angle-ply for maximum bending stiffness. Strain energy was taken as the objective function, while the lamination parameters by which a general laminate construction can be considered were taken as the design variables. Deformation analysis was carried out using the Rayleigh-Ritz method for bending under any loading conditions. Numerical results are presented for graphite/epoxy symmetric laminates, resting on simple supports and subjected to either distributed or concentrated loading. As a result, it was found that the application of the present optimization procedure yielded an optimum design of a laminate construction, and the effects of the loading condition and aspect ratio became clear.
