Elastohydrodynamic Lubrication (EHL): Theory and Definition

05.02.2017 tribonet

Definition of Elastohydrodynamic Lubrication (EHL) Elastohydrodynamic Lubrication – or EHL – is a lubrication regime (a type of hydrodynamic lubrication (HL)) in which significant elastic deformation of the surfaces takes place and it considerably alters […]
