EXPERIMENTAL INVESTIGTION OF THE FRETTING PHENOMENON [PDF]
Fiabilitate şi Durabilitate, 2015 Fretting is now fully identified as a small amplitude oscilatory motion which induces a harmonic tangential force between two surfaces in contact.It is related to three main loadings, i.e. fretting-wear, fretting-fatigue and fretting corrosion.Fretting

An energy description of wear mechanisms and its applications to oscillating sliding contacts [PDF]
, 2003 To quantify wear rates, the Archard approach is classically applied. It relates the wear volume to the product of the sliding distance and the normal load.

A 2D Approach to Predict the High‐Cycle Fatigue Life of Clinched Joints
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.ABSTRACT Clinching is a widely adopted joining technique in the automotive industry, enabling the fabrication of lightweight structures from dissimilar sheet materials. Accurate prediction of the fatigue life of clinched joints is essential for ensuring structural safety and minimizing development costs.

Identification of contact regimes in mechanical components for the evaluation of fretting damage [PDF]
, 2013 In this work the regimes of contact in misaligned crowned splined couplings have been analyzed. Experimental tests have been performed in order to identify if fretting damage on the components appears as fretting wear or fretting fatigue.

Interface roughness effect on friction map under fretting contact conditions [PDF]
, 2010 In many industrial applications where fretting damage is observed in the contact (e.g. rotor/blade, electrical contacts, assembly joint, axe/wheel, clutch) the external loadings or geometry design cannot be changed. Therefore, the surface preparation and

Multiscale analysis of the effect of debris on fretting wear process using a semi-concurrent method [PDF]
, 2020 Fretting wear is a phenomenon, in which wear happens between two oscillatory moving contact surfaces in microscale amplitude. In this paper, the effect of debris between pad and specimen is analyzed by using a semi-concurrent multiscale method.
