N2 - A sequential linear programming method with a simple move-limit strategy is used to investigate the following three important buckling optimization problems of composite shells: (1) optimization of fiber orientations for maximizing buckling resistance of composite shells without cutouts; (2) optimization of fiber orientations for maximizing buckling resistance of composite shells with circular cutouts; and (3) optimization of cutout geometry for maximizing buckling resistance of a composite shell. From the results of optimization study, it has been shown that, given a structural geometry, loading condition and material system, the buckling resistance of a cylindrical composite shell is strongly influenced by fiber orientations, end conditions, the presence of cutout and the geometry of cutout.
