Long term wear of complete contacts subject to fretting

The fully worn configuration of complete, square-edged contacts subject to fretting fatigue is found using a local asymptote, and this is applied to a specific example problem. There are three possible forms of solutions: (a) all wear is averted, (b) there is a finite amount of wear to a stable, fully adhered contact and (c) progressive wear gradually eroding the whole contact. The conditions under which each of these is the anticipated response are revealed.

► We predict the wear extent under the corner of a complete contact.
► Analysis of slip extent under a complete contact.
► Analysis of the stress intensity of crack eminating from the corner of a notch.
► A step further in understanding the initiation of cracks under complete contacts.
