Buckling of ring-stiffened shells of revolution

1989
In previous chapters many examples have been given of buckling of shells of revolution, especially cylinders, reinforced by equally spaced rings or by rings at the edges. Figure 22, which reveals the sensitivity of critical axial load to initial imperfections in cylindrical shells of various wall constructions, seems to indicate that ring-stiffened ...
