An Analysis of Critical Stresses and Mode of failure of a Wire Rope

, and .
(1959)

Abstract

Many wire-rope manufacturers and machine designers are under the impression that the significant stress in a wire rope t"s the tensile stress, or possibly the stress due to tension and bending. This paper proves by mathematical analysis that by far the greatest stress in a wire rope results from Hertz contact stresses at points of contact of wire-onwire, and asserts that the umal mode of failure of a wire rope is f rettingjatigue initiated ut mch points of contact. Design. relationships based on these concepts should be of great value to designers who use wire rope.
