... of the members of the contact being subjected to a cyclic stress (that is, fatigue), which gives rise to another and usually more damaging aspect of fretting, namely the early initiation of fatigue cracks. This is termed “fretting fatigue” or “contact fatigue.” More detailed information on both fretting...
