Hydrostatic collapse tests performed on thick-walled capped cylinders are described. Finite-element predictions which include the effects of end-cap stiffening, cross-section ovalities and material strain hardening are compared to experimental results. The analyses correctly predict the sequence of events leading to collapse, but experimental failure pressures are significantly below predictions. It is concluded that the von Mises yield criterion used in the analysis did not accurately represent the yield behavior of the 1018 steel tubing material of the test cylinders for the triaxial-stress conditions of interest.
