Structural elements in the form of cylindrical shells are often designed to be thin to save weight, and this can lead to buckling. The patterns and values of buckling loads depend greatly on the type of loading, the end support conditions, and effective laminate material properties and couplings. For many typical buckling loadings, there is a variety of similar buckling states, which causes sensitivity to initial imperfections. Understanding this phenomenon requires the consideration of nonlinear strain‐displacement relations, usually in the von Kármán form. In addition, shells of composite materials require deformation assumptions that permit transverse shear deformation. A review of the results obtained using theoretical techniques is given as well as finite element predictions and experimental observations. A very brief summary of references is given for the optimization of shell buckling loads and for the additional effects of stringer reinforcement, thermal loadings, and other topics.

For the optimization of the fundamental natural frequency of stiffened cylindrical shells, simulations were performed for cylindrical shells that were stiffened with between one and five ring stiffeners. ANSYS 11.0 was used to simulate the optimization for the natural frequency. The Subproblem Approximation Method was applied as the optimization method. The design function of the optimization was the geometry of the T-shaped ring stiffener, and the constraint function was the maximum additional volume, constrained to a 10% increase. The objective function of the optimization was chosen to maximize the fundamental natural frequency. The performance index for optimal design was defined as the ratio of the natural frequency to the volume of the unstiffened and stiffened shells. The optimal performance index was obtained for the shell stiffened with three rings.
