The paper presents an optimization approach on laminate configurations of symmetrically laminated plates to maximize buckling loads under combined loading. The coupling between bending and twisting is taken into consideration in the buckling analysis of symmetrically laminated plates. Using lamination parameters, the effect of bending-twisting coupling on the buckling is discussed for the case of simply supported or clamped edges. Optimal laminate configuration to maximize the buckling loads is obtained using a mathematical programming method where four lamination parameters are used as design variables. The relation of laminate configurations and buckling loads is clarified based on a concept of lamination parameters.
