Fretting fatigue is a damage process that occurs when two surfaces in contact with each other are subjected to relative micro-slip, causing reduced life respect the plain case. has now been studied deeply for over 50 years, but still no univocal design approach universally accepted. This review presents literature study involves three main types of mechanical joint affected by fretting (press-f...

Fretting corrosion of as received and shot peened zirconium alloys exposed to high temperature pressure water is tested. High resolution characterization techniques are applied study the microstructure composition worn surface. The results show that peening increases wear resistance material, changing mode from abrasive plus delamination wear. Mechanical promotes alloy by forming a thick dual-l...

BACKGROUND Modular neck adapters for hip arthroplasty stems allow the surgeon to modify CCD angle, offset and femoral anteversion intraoperatively. Fretting or crevice corrosion may lead to failure of such a modular device due to high loads or surface contamination inside the modular coupling. Unfortunately we have experienced such a failure of implants and now report our clinical experience wi...

Submarine power cables (SPC) are vulnerable to fretting, wear, and fatigue due the dynamic environment, particularly at end connectors junctions or other discontinuities, such as seabed features. This paper presents a finite element methodology for global local analysis of fretting between copper conductors in multi-strand cables. The salient inter-wire variables, relative slip contact pressure...

This paper proposes a new methodology for fretting fatigue life assessment. It uses combination of multiaxial criteria, the theory critical distances and node-displacement wear algorithm to account initiation under fretting. Further, extended finite element method is considered compute propagation life. A also introduced predict crack path nonproportional loading conditions. To validate analysi...
