Effect of torsional angle on the fretting wear behavior and fracture failure mechanism of steel wires with spiral contact structure

Journal of Materials Research and Technology
The fretting wear of steel wire will reduce the service life of wire rope and severely threaten the safety of mine hoisting. To investigate the influence of torsion on the fretting wear behavior of steel wire, the fretting wear tests of steel wires with ...

Review and classification of fretting fatigue test rigs [PDF]

, 2011
There is no standard or generally accepted test rig for fretting fatigue experiments. Therefore, researchers adopt an existing concept, or build a new test rig that meets their specific requirements.

Finite element analysis of fretting crack propagation

, 2011
In this work, the finite elements method (FEM) is used to analyse the growth of fretting cracks. FEM can be favourably used to extract the stress intensity factors in mixed mode, a typical situation for cracks growing in the vicinity of a fretting ...

Fundamental problems of fretting wear.

JSME international journal. Ser. 3, Vibration, control engineering, engineering for industry, 1988
Recent studies of fretting wear are reviewed on the basis of work carried out by the author's laboratory. Some of the new findings are introduced below. (1) The critical amplitude to produce severe wear is equivalent to the amplitude when the non-slip region disappears in the elastic contact.

Effect of laser remelting on microstructure and fretting wear properties of APS Al2O3/Y2O3 composite coatings on TC6 titanium alloy

Journal of Materials Research and Technology
To enhance the fretting wear resistance of TC6 titanium alloy, an Al2O3/Y2O3 (81.5 mol.%: 18.5 mol.%) composite coating was prepared on the TC6 substrate using the APS process, followed by laser remelting. The microstructure and fretting wear behavior of

Large-eddy simulations of turbulent flow for grid-to-rod fretting in nuclear reactors

, 2013
The grid-to-rod fretting (GTRF) problem in pressurized water reactors is a flow-induced vibration problem that results in wear and failure of the fuel rods in nuclear assemblies.
