Abstract

Internally pressurized cylinders are used in many industries and they frequently have closed ends of shells of revolution. These closed end shells of revolution are usually torispherical or ellipsoidal shells and they are in common use in fluid cokers in the chemical industry, vessels containing liquid sodium in some fast breeder reactors, storage tanks in the oil industry, containment vessels in the nuclear industry, and water towers.Under internal pressure, compressive forces of considerable magnitude can be generated in the shells. Buckling of these shells in the region of the compressive forces is a distinct possibility.The presence of internal pressure buckling does not generally result in a catastrophic failure but the presence of buckles does raise questions as to the level of confidence in the safety of the shell of revolution. In addition, buckles may interfere with the function of a pressure vessel. For these reasons, the presence of buckles should be avoided in these shells.
