Abstract
In this paper a theoretical model for the elastic-plastic microcontact model of asperities is presemted. Relation
of the contact parameters, such as the mean contact pressure, the contact area and the contact load as a function of the
contact interference are modeled in the elastic, elastic-plastic and fully plastic contact regime. The model is verified by
the experimental results and is compared with published theoretical models. Very good agreement between the present
model and the experimental results are found compared to the prediction of the other contact models.
