Analysis of Fiber-Core Wire Rope

A theory has been developed for the analysis of fiber-core wire rope with multilayered strands. The rope is subjected to both an axial force and an axial twisting moment. The previously developed linear theory for helically shaped wires is used and the equations governing compliance of the fiber core are formulated in a linear fashion. The resultant linear equations are easily solved. The theory is applied to a 6 × 19 Seale fiber-core wire rope and dimensionless results are presented. A load-deformation curve for a Seale fiber-core wire rope is obtained experimentally. Both the theoretically predicted effective modulus of elasticity and the predicted effective Poisson’s ratio of the rope compare favorably with the experimental results.
