摘要：
This paper describes progress in the interpretation of notch fatigue data by re-working the Williams solution to bring out the effects of mode mixity and the limits of small scale yielding. The results are displayed in KI versus KII space. Experimental results from complete fretting fatigue tests using a high strength steel alloy known as super CMV are then plotted out on this diagram and it is shown that the fretting damage does not significantly reduce fatigue life, while the stress localisation effects of adhered pad edges does.
