Introduction,nder a cylindrical flat punch and a sphere that are featured in those works certainly enjoy a high level of prominence. Yet multiple exact solutions exist which are of similar technical relevance to the Hertzian contact problems, but only a limited number of specialists know about these. Among other

Debility

Normal Contact Without Adhesion,iction and no wear. Therefore, normal contact can be regarded as a basic prerequisite for all other tribological phenomena. The solution to the adhesive contact problem, the tangential contact problem, and contact between elastomers can also be reduced to the non-adhesive normal contact problem. In

Normal Contact with Adhesion, bodies. These forces are known as . and, in most cases, cause a mutual attraction. Adhesive forces play an essential role in many technical applications. It is the adhesive forces that are responsible for the behavior of glue, for instance. The well-known theory of adhesive contacts by Johnson, Ken

Torsional Contact,ment along the .-axis in the normal direction of the half-space. If a contact is first loaded with a constant normal force and after that by an increasing torsional moment, a sliding area will propagate inwards from the edge of the contact. In contrast to tangential contacts, there is no theorem for

Wear, and mesoscopic mechanisms causing the macroscopically observable phenomenon of wear are extremely varied and range from abrasive or adhesive debris formation, to the reintegration of previously removed material, to oxidation, and to chemical or mechanical intermixing of the involved surfaces.
