dc.description.abstractStacking sequence design and optimization of 64 layered symmetric-balancegraphite/epoxy laminated composite have been performed. The optimizationproblems aim to find the optimum stacking sequence maximizing the criticalbuckling load by single objective optimization approach. Differential Evolution(DE) and Simulated Annealing (SA) optimization algorithms are proposed tosolve the problems. The effect of the aspect ratios (a/b) and in-plane biaxialcompressive loading ratios (Nx/Ny) on critical buckling load are investigated. Inorder to see the effect of discrete increments of fiber orientation angle oncritical buckling load, 1°, 5°, 15°, 30° and 45° fiber angle increments are alsoconsidered. The results show that (i) the proposed algorithms DE and SAexhibit comparable performance in terms of critical buckling load whencompared Genetic algorithm (GA) and Generalized pattern search algorithm(GPSA), (ii) DE and SA find distinct stacking sequence configurations in termsof buckling load for the same laminated structure design problems.
