Abstract

A simple formula is proposed to calculate the critical buckling load of cylindrically curved composite panels (shallow shells) subjected to external uniform pressure. The buckling load is maximized with respect to the fiber orientation angles in all layers of the symmetrically laminated panel simply supported along the edges. The optimization is processed by following the layerwise optimization (LO) scheme In numerical examples, the optimum layups are obtained both by using the present formula and a general-purpose finite element (FEM) software, and the maximum buckling loads obtained by using the two methods are compared. The accuracy of the formula is discussed by the compassion. The optimum layups are obtained also by FEM and LO scheme for other boundary conditions.
