Design of large diameter cylindrical shells

WebLarge, thin cylinders, each with a diameter of 33 ft, were modeled with imperfections that reduced their load-carrying capacity. Each cylinder model was placed under a uniform axial load to cause buckling. Three different cylindrical imperfections were modeled (see Fig. 4) and analyzed by using NASTRAN's eigenvalue buckling solution.
