The viscosity at the glass transition of a liquid lubricant

open access: yesFriction, 2018
In the classical study of elastohydrodynamic lubrication (EHL) which does not employ real, measurable viscosity in analysis, the possibility of a glass transition has not been considered in many years. Indeed, the two rheological assumptions of classical
