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

Abstract

This article aims at modeling fretting wear in a 2D cylinder-on-flat contact using Winkler elastic foundation model (WK). This model is compared with existing FEM and semi-analytic approaches as well as with experiments where the potentials and limits of the latter are carefully discussed. Following this, WK approach is extended to a 3D sphere-on-flat contact where the results showed that this approach captures nicely the 3D experimental wear profile with lower computation costs compared to semi-analytic approach. Finally, WK approach is applied for more complex cases as reciprocating sliding and fretting wear incorporating a third body layer in both 2D and 3D configurations. Interesting results were obtained confirming the potential of this approach to model complex sliding and geometrical conditions.
