Contact Geometry Adaptation in Fretting Wear: A Constructive Review

Abstract

Fretting is a special type of wear, which appears at the contact interface between two solids subjected to constant normal load and periodic tangential forces. Although most studies on fretting have been executed experimentally, some approaches for simulating fretting wear have also been introduced during the last decades. In particular, fretting wear analysis is concerned with the evolution of the surface profiles of the contacting bodies due to wear, and its modeling was executed using numerical, finite-element, semi-analytical, and analytical methods, including the method of dimensionality reduction. In the present review we discuss recent analytical results on fretting wear contact geometry adaptation.

An Analytical Approach to the Third Body Modelling in Fretting Wear Contact: A Minireview

“…When considering the contact problem with the effect of wear, the issue of contact geometry adaptation [44] should be addressed first. The third body influences the contact pressure distribution not only via the accommodation of the contact displacements, but also via partially filling the variable gap between the surfaces of the first bodies.…”

Fretting wear modeling of 3D and 2D Hertzian contacts with a third-body layer using a Winkler elastic foundation model

“…It is this conforming zone which provides this insensitivity to the elastic stiffness. Besides, Argatov and co-authors revealed analytically, through asymptotic modeling of reciprocating sliding wear, a weak effect of elasticity on surface wear [25][26][27]. Based on this, it seems relevant to apply constant contact stiffness along the simulation which will be more effective especially at large number of cycles where the interface converges to conformal configuration.…”
