Abstract
In this paper a model for the fatigue strength prediction of rope wires is presented and discussed. Within this method the fatigue process of wires is described in terms of propagation of the surface defects caused by cold dr awing. In particular, the fatigue limit is related to the population of ext reme defects and to the material properties expressed by cyclic yield stren gth and by crack propagation thresholds. The model has been successfully applied for the prediction of fatigue stren gth of two different eutectoid steel wires, one of them being zinc coated, used in ropeway applications.
