This is the second edition of a valuable reference source for numerical simulations of contact mechanics useful in fields like civil engineering, car design, aeronautics, metal forming, or biomechanics. Boundary value problems involving contact are of great importance in industrial applications in engineering such as bearings, metal forming processes, rubber seals, drilling problems, crash analysis of cars, rolling contact between car tires and the road, cooling of electronic devices. Other applications are related to biomechanical engineering design where human joints, and implants of teeth are of consideration.
