Abstract

Multi objective optimal design of sandwich composite laminates consisting of high-stiffness
and expensive surface and low-stiffness and inexpensive core layers with respect to cost and frequency is addressed in this paper. Discrete ply angles and number of low-stiffness core layers are considered as design variables and simulated annealing algorithm is used for simultaneous cost minimization and frequency maximization. The proposed model is applied to a graphite-epoxy/glassepoxy laminate and results are obtained for various aspect ratios and number of layers.
