摘要：

The contact for donut-shaped asperity has been investigated for decades based on two-dimensional Hertz contact. In this paper, the contact is investigated by finite element analysis. The results show that two-dimensional Hertz contact can predict the contact only for the donut-asperity with large radius. Thus, new semi-empirical equations are proposed. The total load, load-indentation depth relations and the coordinates of contact edges can be predicted accurately by semi-empirical equations. For the donut-asperity with small radius, the modified model can predict the contact.
