Abstract

Fretting fatigue is particularly damaging because it can affect both the initiation and propagation phases of crack life. In the preceding chapter its effect on propagation was discussed and it was shown that in this phase of the crack’s life the problem can be reduced to that of analysing cracks growing in a particularly severe and complex stress field. The effect of fretting on crack initiation is likely to be far less amenable to analysis since initiation will take place at a microscopic level. Nevertheless the area is important for the study of fretting fatigue since initiation can take up a significant proportion of crack life under some conditions. Before discussing crack initiation in fretting fatigue, however, it is appropriate to discuss the nature of crack initiation in general and to highlight a few important features.
