Influence of microgeometry in the point contact zone of rest friction on fatigue life for friction bearing units

Abstract

A comprehensive methodology has been developed to assess the maximum contact stresses and deformations in the point contact zone and the maximum tangential stresses, including their position in the subsurface zone in depth and in the rolling direction when the microgeometry of the rest contact.
