Multi-objective design optimization of composite laminates using discrete shuffled frog leaping algorithm

This paper deals with the optimization of composite laminates using discrete shuffled frog leaping method. This approach is used to find optimal values of three design variables including fiber orientations in matrices, thickness of each ply and number of layers in order to minimize the weights and costs of the laminates under various loading cases. Three well-known failure criteria are employed to investigate the capability of the plate in bearing the applied loads. Moreover, the comparison of the obtained results with previously reported results is performed to prove the applicability of the algorithm in optimizing composite materials.
