Hydrodynamic journal bearings in internal combustion engines suffer progres-sively from hindered operation conditions. Consequently the chance of wear and failure increases making wear prediction and simulation inevitable. For the purpose of numerical wear evaluation we implemented a modified Archard’s wear law in COMSOL Multiphys-ics® and applied it on a test rig. Necessary wear coefficients were determined based on close-to-component tribological wear tests. By comparing numerical and achieved test results the usability of the developed methodology was evaluated. Results reveal the suita-bility to assess wear locally and chronologically resolved.
