Karim N. Elkholy, Auteur ; M. M. Khonsari, Auteur |An investigation on the nature of stick-slip associated with granular materials sheared between two parallel disks within the context of granular lubrication is presented. Experiments are carried out in an annular shear cell apparatus to demonst[...]

Saleh Akbarzadeh, Auteur ; M. M. Khonsari, Auteur |A model is presented, which enables one to predict the running-in performance of the rolling/sliding surfaces subjected to mixed-lubrication line contact. The load-sharing concept was used, in which it is assumed that both the fluid film and the[...]

Ilya I. Kudish, Auteur ; P. Kumar, Auteur ; M. M. Khonsari, Auteur |The estimation or prediction of elastohydrodynamic lubrication (EHL) film thickness requires knowledge of the lubricant properties. Today, in many instances, the lubricant properties have been obtained from a measurement of the central film thic[...]
