A study of how a cylinder behaves when it is subjected to a transient external pressure. In this Memorandum, only the instability of the cylinder is examined. This is termed dynamic stability, since the loading is time-dependent. The motions in the three principal directions of a cylinder are purposely considered together to see the influence of their interaction on the mode of failure, compared to earlier work for a single motion. The results show that the mode of failure varies with geometry, numbers of buckle waves for a given loading, and material selected. The influence of the loading rate is also studied.
