The buckling strength of fiber-composite laminate shells with given loading condition and material system is maximized with respect to fiber orientations by using a sequential linear programming method together with a simple move-limit strategy. Significant influence of shell thickness and shell length on the optimal fiber angles, the critical buckling loads and the critical buckling modes of fiber-composite laminate shells has been shown through this investigation.
