Abstract: | In this paper applications of multicriteria optimization to design hybrid laminates is shown. In the considered numerical example, the obtained preferred solution is 30% heavier than Carbon/Epoxy laminate and use a third of the more expensive material. Moreover, a small number of layers is needed to build an optimal solution. In the case of scalar optimization three layers are required. In the case of bicriteria optimization one E-Glass/Epoxy layer placed between four Carbon/Epoxy layers is enough to build an optimal laminate. Two criteria may lead to a set of preferred equal solutions. Thus, connection of Pareto concept with a lexicographic order by introduction of an additional criterion is useful for ordering them. A similar approach may be used for designing hybrid laminates with a requirement of a compromise between the stiffness and cost of a plate. (© 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) |
