Fretting Fatigue Characterization of Steel Bolted Connections
Fretting fatigue is a multiaxial stress problem, which occurs on contacting components under normal pressure while they are subjected to cyclic loads and oscillatory relative movement of small amplitudes at the same time. Slip-critical bolted connections are commonly used in repetitive loading …

An investigation into the mechanisms of fretting fatigue
… of the mechanismsinvolved in the process of fretting fatigue.The design and construction of a rig to enable acontrolled fretting action to be applied to a push-pulltype of fatigue specimen is discussed. Specialconsideration is given to the form of the fretting contactgeometry with regard to …

A study of fretting fatigue in aircraft components
… and experimental approaches to the problem of fretting fatigue in materials systems relevant to aircraft components. The basic contact mechanics for fretting fatigue in a sphere-plane contact geometry are reviewed. Various elastic criteria for predicting fretting failure are discussed; selected …

A study of fretting fatigue incorporating sharp corner contact geometry.
Fretting fatigue occurs when components are in contact and subjected to cyclic loads or vibrations. The following research programme investigates the fretting fatigue phenomenon using a specific flat contact geometry encompassing sharp comers. The pressure distribution at the contact interface is …

A unified fracture mechanics approach to fretting fatigue crack growth
… the adequacy of a modeling approach of fretting fatigue for a sphere-on-flat geometry entirely based on fracture mechanics. All stages of damage evolution, from initiation to failure, are encompassed within the framework of fracture mechanics, in contrast with the general use of stress …

Fretting fatigue Behaviour of Inconel 718 at room and high Temperature
This thesis analyses the fatigue behaviour of Inconel 718, a Nickel-Chromium-based superalloy known for its excellent mechanical properties and high resistance to corrosion and oxidation, even at elevated temperatures. The study combines experimental testing and numerical simulations in order to …

Contact fatigue : life prediction and palliatives
Fretting fatigue is defined as damage resulting from small magnitude (0.5-50 microns) displacement between contacting bodies where at least one of the bodies has an applied bulk stress. The applicability and limits of a fracture mechanics based life prediction is explored. Comparisons are made …
