Abstract
It is shown on the basis of the theory of cyclic strain-induced heating of plastics that two forms of fatigue fracture are possible (thermal and mechanical), this being reflected in the fact that the appropriate Wöhler curves consist of two branches. The conditions under which a transition from one form of fracture to another takes place are analyzed, and the theoretical predictions are proved by experiment.
