Bending fatigue tests are taken normally until the break of the rope or a strand. The exact point of discard can be determined by evaluating the single rope sections.
Predicting the service life of high-strength fiber ropes in CBOS (cyclic bend-over-sheave) fatigue has been the subject of many recent studies. Accurate lifetime prediction is critical to reduce risk of
As a result, this research aims to evaluate the fatigue behavior of hollow cylindrical specimens con-sisting of carbon fiber reinforced with an epoxy matrix for two alternative fiber lay-up configurations
This paper aims to contribute to the understanding of the fatigue behavior of unidirectional flax fiber-reinforced epoxy composites through systematic experimental investigations.
Due to the fact that the lifetime of ropes is directly proportional to the number of bending cycles, the number of bending cycles should be as small as possible for each specific rope section.
The experiments of high-strength steel-fiber-reinforced concrete (SFRC) beams subjected to fatigue bend loading were conducted in this work. A total o

In this paper we describe results for the cyclic fatigue behavior of high strength fused silica optical fibers as a function of stress amplitude and frequency in the range of zero to 100 Hz.
In this context, CETIM and its industrial partners have launched, within a working group, a research program to evaluate the fatigue performance of synthetic ropes subjected to periodic
This paper aims to explore the bending fatigue behavior of carbon fiber SMC composites by utilizing both experimental and numerical methods. First, four-point bending fatigue tests are performed with
Abstract One of the limitations of synthetic fiber ropes in industrial uses has been the premature wear of these materials when subjected to continuous bend-over-sheave fatigue.
In this work, several fatigue experiments, temperature analyses, and digital light optical microscopy were carried out to evaluate the influence of pulse
In this work, several fatigue experiments, temperature analyses, and digital light optical microscopy were carried out to evaluate the influence of pulse duration on
