Abstract
This paper deals with optimal design of sandwich composite laminates consisting of high- stiffness and expensive surface and low-stiffness and inexpensive core layers. The
objective is to determine ply angles and number of core layers in such a way that natural frequency is maximized with minimal material cost. A Genetic Algorithm (GA) procedure is
used for simultaneous cost minimization and frequency maximization. The proposed model is applied to a graphiteepoxy/ glass-epoxy laminate and results are obtained for various
aspect ratios and number of layers.
