This thesis deals with the problem of a thin fluid flow in narrow interfaces between contacting solids subject to a normal loading, which is relevant for a range of tribological and engineering applications, as well as for geophysical sciences. The treatment of this problem requires coupling between fluid and solid mechanics, further complicated by contact constraints and potentially complex geometrical features of contacting surfaces. In this thesis a monolithic finite-element framework for handling frictional contact, thin incompressible viscous flow and transfer of fluid-induced tractions to the solid is developed. Additionally, we considered fluid entrapment in "pools" delimited by contact patches and formulated a novel trapped-fluid el...
