Abstract
Optimum fiber orientations of symmetrically laminated cylindrical pressure vessels are determined subject to strength constraints which contain fuzzy input data. The fuzzy information is taken into account by defining fuzzy feasible regions for the constraints with the degree of membership of any design point depending on the degree of satisfaction of the constraints. The maximum stress theory of failure is adopted in determining the burst pressure. Membership functions are defined for the objective function (internal pressure) and the constraints, and the degree of membership is maximized with respect to ply angles. Numerical results are given for vessels made of a graphite/epoxy material. The behavior of the optimum ply angles and the maximum pressure is investigated with respect to the level of fuzziness and axial forces.
