An approach to investigate surface roughness influence on non-lubricated and lubricated contacts by means of the finite element analysis = Ein Ansatz zur Untersuchung der Oberflächenrauheiteinflüsse bei geschmierten und trockenen Kontakten mittels der Finite Elemente Methode

Present thesis develops a numerical analysis framework to investigate the mixed lubricated contacts of two rough surfaces by means of the finite element method. A verification has been done to check the convergence of the microscopic mixed lubrication model. Parameter study done for the mixed lubrication model displays the contact stresses and temperatures and shows which parameter had the most influence on the friction behavior.
