Abstract:

Twenty thin-walled circular cylindrical shell specimens were provided with end plates and were ruptured through the application of an internal hydrostatic pressure. The specimens were manufactured by electrodepositing nickel and incorporated simulated weld flaws. It was found that short flaws corresponding to a misalignment along weld seams running in the circumferential direction reduced the bursting pressure much less than similar flaws along weld seams running in the axial direction. As a matter of fact, in the former case the reduction in the bursting pressure was only of the order of magnitude of 5 percent when the flaw had a depth or offset of 3.5-times the wall thickness.
