Abstract: This paper presents a macro/micro scale finite-element local-refinement model developed in order to analyse mixed-lubrication conditions in Internal Combustion (IC) big-end conrod bearings. The initial coarse mesh is refined in the mixed-lubrication contact zones to obtain a good-enough representation of the contact pressure. The flow factor method and a statistical elasto-plastic asperity contact model are included. The results show important differences between the classical TEHD and the local-refinement model, especially in the estimation of the asperity contact pressure.
