“…These load and environment factors, alone or in combination, have been shown to result in premature failure of the wire ropes. [3][4][5] The combinations of complex wire rope geometry, combined loading, and operating environment render the accurate prediction of the useful life of the wire rope a challenging task. Consequently, an efficient, yet accurate fatigue life prediction model 6 is indispensable in the fast generation of reliable data for the safe and reliable design of the wire ropes.…”

Fretting fatigue contributes significantly to the fatigue failure process in steel wire ropes at the wire‐to‐wire trellis contact region with partial slip conditions. In this respect, this work demonstrates a new damage‐based fretting fatigue model for the prediction of such a failure process. The model is based on Lemaitre's damage equations for quasi‐brittle material with a damageable micro‐inclusion embedded in an elastic meso‐element. It incorporates the cyclic degradation of the elastic modulus of the drawn steel wire material. The fatigue life model acknowledges the mean stress effect. The constitutive and damage equations are formulated into user material (UMAT) subroutine for integration with Abaqus finite element analysis code. The localized fretting fatigue damage mechanism is simulated with an isolated two‐wire model. The effect of the contact condition with the coefficient of friction of 0.2 and 0.8 on the contact mechanics of the drawn wires is considered. The fretting fatigue mechanism map is established for each simulation case. The simulated results of N0 (no of cycles to initiate damage) and damage variable, D, confirm the fretting fatigue condition as the damage occurs in the slip region of the contact area for both the frictional conditions. The results were found in agreement with the previously establish Ruiz fretting parameter. This study will provide a base for the onward reliability assessment of steel wire ropes.

“…Few reports have been made for larger-diameter wire ropes [3][4][5] and the fatigue tests conducted have given no specific definition of fatigue life. The best attempt has been visual examination of broken wire in the outermost layer of the wire rope.…”
