Abstract
The article presents a new empirical mathematical model for describing the change in the actual contact area of metals depending on the friction path, including such characteristics as the sharpness of the change in the actual contact area, the initial intensity of the change in the actual contact area, the increment in the intensity of the change in the actual contact area, the value of the friction path corresponding to the minimum "acceleration"of changes in the actual
area of contact. The validity of the developed mathematical model is shown for the friction of pyramidal indenters made of aluminum, copper and steel St.3 on a steel surface.
