The Use of Almost Complete Contacts for Fretting Fatigue Tests

Source

In this paper we analyse the frequently used bridge-type fretting fatigue tests, by idealizing the specimens as having almost-flat-ended feet, but with small blend radii. An estimate of the shearing force developed is given, and the relevant partial slip contact problem is solved. We then go on to examine further characteristics of the problem such as the local density of energy expenditure against friction, and the crack tip stress intensity factors found for cracks.
