Mining Publication: Wire Rope Research: Analysis of Bending Fatigue in a 2-Inch IWRC Wire Rope

January 1993

A unique machine for inducing bending fatigue in wire ropes was built at the U.S. Bureau of Mine's Pittsburgh Research Center. This machine can produce nine levels of degradation through repetitive cycling of long samples of wire ropes of the types used in the mining industry. This report provides an analysis of the results of the first wire rope to be fatigued on this machine. These results have indicated that as a wire rope accumulates bending cycles, its strength first decreases because of wear and then increases due to cold working of the wires. As the amount of cold working increases, more and more of the embrittled wires break and the strength of the rope decreases rapidly. In this test, application of several of the regulatory retirement criteria to various sections of the rope suggests that there may be some inconsistency among them.
