Description
Summary:	Several partially corrugated circular cylinders were tested to destruction under uniform external pressure. Some of the vessels failed by inelastic general instability and some failed by a local buckling mode, which was neither the classical shell instability mode nor the classical general instability mode. The experimentally obtained buckling pressures were found to be related to the magnitude of the initial out-of-roundness for the vessels that failed through inelastic general instability. The theoretical buckling pressures showed virtually no relationship with the experimentally observed buckling pressures, for the vessels that failed via the local buckling mode.
