    Models based on fracture mechanics are developed in order to describe crack growth in fretting fatigue. Particular attention is given to a recently developed model, the ‘Crack Analogue’ in which certain aspects of equivalence are recognized between contact mechanics and fracture mechanics. Here, an analogy is invoked between the sharp edged contact region between two contacting surfaces and the geometry of the near-tip regions of a double edge-cracked plate. Based on this approach, a new life prediction methodology is developed for fretting fatigue.
