Failure experiments on nine thin-walled cylinders whose lateral sides were subjected to uniform external pressure were conducted, for the purpose of finding the method of determining the initial out-of-roundness of actual cylinders to be used in the existing theoretical formulae for the failure pressure. The cylinders for the present experiments were of such dimensions that their computed values for yielding failure pressure were smaller than those for elastic buckling pressure, if the cylinders were completely round. The investigation revealed that : (1) The initial out-of-roundness need not be taken into consideration on the calculation of the failure pressure for the relatively round cylinders as the machined cylinders used in the present experiments. (2) It is appropriate to determine the initial out-of-roundness by a method similar to that suggested by Holt for the relatively unround cylinders as the plate-worked cylinders.
