The best layup for a hybrid laminated cylindrical shell subject to a buckling load constraint is determined. The objective of the optimization is the minimum weight design of these structures. The ply angle is taken as the design variable. Various configurations of graphite and boron epoxy are considered in order to determine an optimal stacking sequence. The symbolic computational software package MATHEMATICA is used in the implementation and solution of the problem. Results are given illustrating the dependence of the optimal layup on the cylinder length and radius.
