All lubricants contain particles. These particles are both initially present in the lubricant and mechanisms (manufacturing process, storage ); generated during running-in, through wear and corrosion; or come from external sources. These particles damage the surfaces, creating indents when they are squashed in the contact. These indents increase the fatigue failure risk inducing pressure and stress perturbations. This work is based on a dry and lubricated (EHL) contact study. The Reynolds equation for Newtonian fluids is used. Multigrid and multi-integration techniques are used to limit computing time. The aim is to predict pressure and stress distribution perturbations, and finally to predict the life reduction of indented contacts as a fu...
