“…Where wear degradation and fatigue stress are dominant, Seale-type co-twisted and cross-twisted steel wire rope is chosen. Juan Felipe Beltran et al [18] used experimental and analytical methodologies to investigate the static response of asymmetrical damage to metallic strands of steel wire rope. Damage strands of multilayer strands are regarded as uncoupled biaxial bending and axial stress 1D nonlinear beams.…”

Underground mining is a difficult area for miners to work. Miners must go to the working faces by walking, which is not only time consuming but also physically demanding. In mines, a man-rider chair lift system (MRCL) has been developed to alleviate the strain stresses caused by walking lengthy and uneven distances up to the working faces. All parameters, including horizontal and vertical distances, variation and inclination of underground mines, slope forces considering the weight of persons and chair, forces acting towards return and drive unit, curves angles, power to operate, and rope safety factor, are calculated mathematically while modelling a man-rider chair lift system for both the installation and extension phases. We analyzed the analytical approach in conjunction with practical installation of the man-rider chair lift system to establish if the installation and extension of MRCL is genuinely feasible in the current scenario. We also created a simulation model of steel wire rope in Creo 8.0 for analyzing the various stresses on it with the Ansys R 16.2 software. In both phase I and phase II, the factor of safety is above that recommended, and the system is a hundred percent reliable, risk-free, and safe for operation.

“…However, this is a challenging task because of the complex geometries of cables and the difficulties associated with obtaining a high-quality mesh, which is necessary to accurately reproduce the stress/strain fields that are produced in the cable. Although several studies have been carried out using finite element formulation, [17][18][19][20][21] only a few have developed accurate finite element models (FEM) including friction, plasticity, and a good mesh refinement around contact zones. 22,23 Nevertheless, although these models reproduce the global response and contacts stresses between cables with high accuracy and low computational cost, the use of these models is limited since it requires a complex mathematical implementation.…”

Fatigue failure of cables and strands is a common and complex problem. Failure is typically caused by different combinations of time‐variable bending and axial forces. In addition to these loads, contact stresses between wires may play an important role in the fatigue failure of cables. The present work aims to provide deep insight into the fatigue failure of a seven‐wire stainless steel strand subjected to a combination of variable axial and bending loads. To avoid side effects in the analysis, fatigue failure of the strand close to the clamps is prevented. Several tests were performed with a new device specifically designed to avoid failure near the clamps. Thus, failure is always produced at the middle length of the specimen. Test simulations were performed by employing the finite element method. The numerical results were validated via comparisons with experimental data. Finally, life prediction curves were obtained.
