Abstract

This article discusses two very different points of views of the behaviour of plastically deformed asperity contacts with friction loading. A fundamental mechanics study is carried out using the concept of contact hydrostatic pressure. The study reveals various features of the two view-points. Some literature results are subsequently analysed. The analysis suggests that the friction force may significantly reduce the contact hydrostatic pressure thereby reducing asperity load capacity along with other consequences in the tribo-systems. This article may increase the understanding of the behaviour of asperity microcontacts and may be useful for future modelling of frictional contact of rough surfaces.
