✦ Synopsis

In each of the two case studies described in this paper a vessel containing a pressurised fluid failed by the phenomenon of external-pressure buckling. In the first case study a jacketed reactor vessel developed an inward-facing bulge because the heat-transfer oil in the jacket had expanded during a temperature excursion. The second case study involved the "snap-through" of a spherical-cap partition in an oil storage tank. The partition had been subjected to an unacceptably high external pressure because compressed air had been used to propell a fresh supply of oil into the storage tank. The buckling failures were analysed using standard results for the external-pressure buckling of thin-walled tubes and spherical caps, and the critical collapse pressures were found to be of a suitable magnitude to account for the failures.
