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. •Application of Winkler model (WK) to simulate fretting wear in 2D & 3D Hertzian contacts.•WK model provides good predictions for wear depth exceeding 5% of the contact radius.•2D simulations show that WK is 300 times faster than FEM.•Winkler model simulates well complex 3D contacts including third body layer.•Comparison of Winker approach with FEM and semi-analytic models and experiments.
