N2 - Based on the sequential linear programming technique, an effective optimization method and its associated algorithm are developed suitable for a systematic study of buckling stability and design of fiber composite laminate shell structures with complex geometry under general loading. Accuracy and efficiency of the currently developed solution procedure are demonstrated. The optimization method is used to study 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.
