The fracture of cables is often caused by fatigue phenomena. To analyse the fatigue behaviour of these elements, a device has been designed, manufactured, and validated. This machine can produce different load states for the specimens, combining variable axial loads and variable bending moments. The testing machine has been designed to achieve two goals: to avoid the fracture of the cable in the vicinity of the clamps and to assure that the fracture of the cable is in the middle of the length of the specimen. The type of failure will be due to a combination of global stresses and fretting fatigue phenomena. This work also shows the results of different fatigue tests for a specific strand configuration. Finally, the fracture and contact surfaces of the strand have been analysed with a scanning electron microscope (SEM). The results obtained with this device show that it is adequate for testing cables and strands subjected to different combinations of axial loads and bending moments.

“…For example, in hoisting construction, when under working condition, steel strands are always in the alternate load‐unload effect state; when under resting condition, the steel strands are in no load state. And when the steel strands are used as cables in the engineering structure, they are always in different load states when subjected to different working conditions . Some researchers have studied the mechanical performance of steel strands in different load conditions.…”

To study the physical and mechanical performance and damage mechanism of steel strand under coupling effects of load and environment, with the changing parameters of different corrosion time and load forms, 16 groups with totally 32 specimens were designed under coupling effects of load and environment. The test results show that the corrosion weight loss rate Pw presents the increasing trend with the increase of corrosion time, but the increasing rate gradually decreases, and the Pw increasing trend accords with the Boxlucass function model. The tensile strength of specimens presents the decreasing trend with the increase of corrosion time in the stage of etch pits nucleating and expanding, but the decreasing trend is relatively small, within 5%. The Pw of specimens under alternate load working condition is the biggest; under static load condition follows and under no load condition is the lowest. Different load forms have little effect on the tensile strength. Based on Boxlucass function model, the relationship between Pw and corrosion time under different load forms were fitted out, respectively. The research results can provide reference for some related research.

“…The mechanics of the wire ropes under tensile loading has been well researched [8]. In the latter, the fatigue design of wire ropes considers both the high-cycle fatigue of the stranded wires and the inherent fretting effects [9][10][11][12]. The much-needed fatigue-life data (S-N curves) for the wire ropes are based on data taken from available standards such as DNV OS-E301 (DNV, 2004) and the available literature [1,[13][14][15][16].…”

This paper describes a newly-developed damage-based fatigue life model for the longterm reliability assessment of drawn steel wires and wire ropes. The methodology is based on the computed local stress field in the critical trellis contact zone of a stranded wire rope by FE simulations and the estimated fretting damage of the drawn wire material. A case study using a single strand (1x7) steel wire rope with 5.43 mm-dia. drawn wires is employed to demonstrate the damage-based fatigue life prediction procedures. Under applied tensile loading with peak stress corresponding to 50%MBL (P = 145 kN, R = 0.1), the von Mises stress cycles in-phase and with an identical stress ratio to the applied axial load. The damage initiation life at the trellis contact along the core wire is No = 673 cycles with an additional 589 load cycles to reach the first separation of the material point. The threshold load cycle for the fretting fatigue damage is predicted to be 12.3%MBL. An improved data set of the damage model parameters of the drawn steel wires is indispensable in achieving an accurate and validated life prediction model.
