A reliable engineering analysis technique has been developed to predict the buckling load and bearing capacity of stiffened composite panels. Based on this technique and sensitivity analysis of design parameters related to buckling and post-buckling performance, a structural optimization design method has been proposed for composite panels considering buckling and post-buckling.
