A Stress-Criterion-Based Model for the Prediction of the Size of Wear Particles in Boundary Lubricated Contacts
In this paper, the formulation and validation of a model for the prediction of the wear particles size in boundary lubrication is described. An efficient numerical model based on a well-established BEM formulation combined with a mechanical wear criterion was applied. The behavior of the model and particularly the influence of the initial surface roughness and load was explored. The model was validated using measurements of the wear particles formed in steelâsteel and steelâbrass contacts. In the case of steelâsteel contact, a reasonable quantitative agreement was observed. In the case of steelâbrass contact, formation of the brass transfer layer dominates the particles generation process. To include this effect, a layered material model was introduced
