      abstract     = {Machine elements and mechanical components have often
                      surfaces with anisotropic roughness, which may result from
                      the machining processes, e.g. grinding, or from wear. Hence,
                      it is important to understand how surface roughness
                      anisotropy affects the contact mechanics properties, such as
                      friction and the interface separation, which is important
                      for lubricated contacts. Here we extend a multiscale
                      mean-field model to the lubricated contact between a soft
                      (e.g. rubber) elastic solid and a rigid countersurface. We
                      consider surfaces with anisotropic surface roughness, and
                      discuss how the fluid flow factors and friction factors
                      depend on the roughness power spectral density, as well as
                      on the location of roughness on the interacting solids.
                      Finally, we present an experimental study of the lubricated
                      sliding contact between a nitrile butadiene rubber O-ring
                      and steel surfaces with different kinds of isotropic and
                      anisotropic surface roughness. The good quantitative
                      comparison between the experimental results and the theory
                      predictions suggests that the multiscale lubrication
                      mechanisms are accurately captured by the theory.},
