... of the crack behavior are shown in Fig. 17 and 18 . Wire rope can fail by fretting fatigue. As the rope flexes, wire strands rub against each other and produce fretting at the wire-wire contacts. If the fretting occurs in a zone that is also subject to cyclic fatigue stresses, failure occurs. An example...
