Fretting generally results in either material removal or fatigue, a combination of both. Although the term is rarely used now, early literature addressing this subject, fretting that resulted was sometimes termed “ corrosion ” on account characteristic oxide debris emanated from such contacts, with description itself encapsulating understanding has both mechanical and chemical nature. When aspe...

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...

Abstract The fatigue process under fretting conditions is characterized by small oscillatory movements due to vibrating or cyclic loads between two surfaces in contact. Two phenomena can arise as a consequence: the surface wear of bodies contact, giving rise so-called wear. second phenomenon concerns crack nucleation contact region, causing reduction strength component subjected loading. This c...

The present paper discusses the formulation of weight functions for inclined edge cracks in finite width plates, typical Rolling Contact Fatigue defects, to obtain Stress Intensity Factor and T-stress. Because do not depend on load boundary conditions, their use is convenient study subjected complex stress fields, e.g. fretting fatigue rolling contact fatigue, since field calculated uncracked g...
