Advanced fiber-reinforced composite materials have been used for structural members, because of their high specific strength and stiffness. In general, laminated cylindrical shells behave differently from isotropic and homogeneous orthotropic cylinders due to the effect of lamination constitution associated with their anisotropy and unsymmetric lamination.
In this paper, the effect of lamination constitution on the buckling stress of carbon fiber/epoxy (CFRP) angle-ply laminated cylindrical shells under bending is reported. The effect of various factors, such as stacking sequence, number of layers, lamination angle, dimension of cylinders, and buckling modes, on the buckling value are analyzed by assuming the buckling patterns which satisfy the Flügge-type equilibrium equations. It is clarified that the buckling stress is significantly affected by the effect of lamination constitution.
