  • ABSTRACT: Optimum stacking sequences of laminated composite beams are investigated for minimum normal and shear stresses by the use of two different failure criteria for different boundary conditions. The stacking sequence optimization is carried out by genetic algorithm (GA) optimization technique. Fiber orientation angles are used as the design parameters. During the optimization process, Tsai-Wu and Tsai-Hill failure criteria are both used as a control mechanism in the algorithm for each generation. Since the minimization of bending stress parameters and failure analysis are performed at the same time, convergence and reliability of the optimum stress values are improved respectively.
