This note is concerned with the rupture of hydrodynamically lubricated films in infinitely-wide non-conformal contacts. An attempt to correlate previous experimental work with new analytical results using separation cavitation boundary conditions is reported. The correlation shows no overall improvement compared with that obtained using analytical results employing the more common Swift–Stieber boundary conditions. It is suggested that a more detailed examination of the physical processes at work when rupture occurs in dynamically-loaded thin-film contacts is needed.
