✦ Synopsis
This paper contains details of recent developments in the analysis of elastohydrodynamic lubrication problems using the finite element method. A steady state isothermal finite element formulation of the smooth line contact problem with Newtonian lubricant behaviour is presented containing both first-and second-order formulations of the hydrodynamic equation. Previous problems with the limited range of applicability of both first-and second-order finite difference solutions have been overcome by summing both the first-and second-order equations' weighted contributions. Application of the method to a range of problems unattainable by either single first-or second-order formulations is presented.
