Abstract
An experimental determination of the interframe buckling collapse of a ring stiffened cylinder subjected to hydrostatic pressure is presented. This test served two purposes, the first to experimentally verify finite element predictions of the buckling collapse behaviour, the second to evaluate the possibilities of using an existing high pressure facility for conducting model tests of more complex pressure vessel models. The finite element and experimental results for the collapse load and mode were in good agreement. A method of determining the elastic buckling collapse load by measuring the decreasing frequencies of vibration modes corresponding to buckling collapse modes has also been investigated with encouraging results. The high pressure tank served the purpose of conducting the experiment, although the inability to physically observe the test did cause some difficulties in determining the actual collapse load.
