چکیده:

In this paper, stacking sequence optimization of laminated cylindrical shell for obtaining maximum natural frequency and buckling stress simultaneously has been studied. Anisotropic cylindrical shell has finite length with simply supported conditions at both ends. Three dimensional elasticity approach is used for free vibration analysis and buckling stress function is based on theory of classic shells. Genetic algorithm is used for optimization and regarding our two-objective problem, Pareto-optimally curve is used to help determine the way to simultaneously satisfy all objectives. Finally numerical results are presented for optimization of a six-layer cylindrical shell.
