Efficient finite element simulation of full-system elastohydrodynamic lubrication problems [PDF]
, 2012 This thesis is concerned with the efficient numerical solution of problems of elastohydrodynamic lubrication (EHL). Our approach is to consider fully-coupled models in which the governing equations for the lubricating film, the elastic deformation and ...
