The purpose of this work is to shed light on the problem of the fretting damage of a mechanical assembly bolted in three dimensions. This study requires the analysis of the stress fields in the Cartesian coordinates in terms of the angle and the radius of... see more

The fretting behavior of nuclear fuel assemblies is influenced by a number of parameters. One of these is the fit between the fuel rod and the spacer grid, which changes during the fuel residence time in the core. The influence of fit on fretting has been... see more

Fretting damage to fuel rods reduces the service lives of the fuel assemblies and therefore increases reactor operating costs. The future development of fretting-resistant spacer grids necessitates the investigation of fretting behavior by means of model ... see more

In this paper, the fretting damage of a mechanical bolted assembly in three dimensions is studied using a numerical approach. The study consist to analyze the cylindrical coordinates in stress fields and other fretting parameters depending on the angle an... see more

The effect of steel disc surface texturing on dry gross fretting in a ball-on-disc configuration was studied. Dimples were created with abrasive jet machining. The tribological performance of sliding pairs, steel–steel and steel–ceramics, was ... see more

This paper describes statistical determination of fretting-induced failure of an electro-deposited coating. A fretting test is conducted using a ball-on-flat plate configuration. During a test, a frictional force is measured, along with the relative displ... see more

In this study, efforts were made to oxidize the Ti3SiC2 coating surface to improve its wear resistance by producing oxide layers and healing microcracks that initiated from the thermal sprayed process. Tribological behaviors of the thermal oxidation-treat... see more

  Abstract. Wear is a failure mechanism that takes place on the contact interface of solids in relative motion. For instance, in the oil & gas industry wear can be observed on chain links and connectors of the mooring system. In this work, we an... see more

Fretting occurs whenever the interface between components is subjected to a variable load, since it creates a finite relative tangential displacement over at least part of the contact zone. This phenomena has been the focus of many researches for being on... see more
