The local pattern of initial of fracture of machine parts is discussed and the practical significance of determination of
the zone of manifestation is highlighted. The temperature is considered the main factor in the process of improvement of the
thermal friction problem governing operation of a heavily stressed contact. The results of calculation of brakes with the
method of thermal dynamics of friction and wear are demonstrated.
Key words local fracture - zones of maximum local wear - local contact sport - interfaces of real dimensions - thermodynamics of friction and wear
