Multi-scale analysis of the roughness effect on lubricated rough contact [PDF]
, 2014 Determining friction is as equally essential as determining the film thickness in the lubricated contact, and is an important research subject. Indeed, reduction of friction in the automotive industry is important for both the minimization of fuel ...

A model for deformable roll coating with negative gaps and incompressible compliant layers [PDF]
, 2003 A soft elastohydrodynamic lubrication model is formulated for deformable roll coating involving two contra-rotating rolls, one rigid and the other covered with a compliant layer. Included is a finite-strip model (FSM) for the deformation of the layer and
