| Description |
The bellow subassembly of the gimbal joint has failed by fatigue. Almost all the convolutes of all three plies of the bellow were found to have fatigue cracks. Investigation revealed that the fatigue cracks have initiated at the weld-parent metal interface and propagated progressively in the circumferential direction. A sharp change in profile at the weld-parent metal interface appears to have resulted in severe stress concentrations leading to fatigue crack initiation. No metallurgical abnormalities were found responsible for the failure and fatigue appeared to be stress related.
