Fatigue resistance at variation of temperature-time factors

The equations of an elasto-plastic static and cyclic deformation at high temperature, force and deformation criteria of quasistatic and fatigue failures, criterion of initiation and propagation of cracks, features of the equations for linear and nonlinear fracture mechanics are described. The mechanics of a nonlinear deformation and fracture is used for calculations of strength, life-time and crack resistance of constructions at high temperature
