Two-parameter fracture mechanics

The main provisions, models, criteria and experimental methods are given by double -parametric elastic and elastoplastic mechanics of destruction of bodies with cracks and cuts. Particular attention is paid to modern ideas about the asymptotic field of voltages, deformations and movements in the vicinity of the top of the crack (cut) The results of a three -dimensional study of the parameters of local constraint of deformation in the tasks of destruction mechanics are given. Models of double -parametric mechanics of destruction are adapted to solving the problems of the fatigue and dynamic spread of cracks, the evolution of the parameters of the mechanics of destruction in heterogeneous fields of residual stresses and damage, braking of cracks, and searching for a crack trajectory. The basic provisions and methods of determined and probabilistic calculations for strength according to the criteria for two -parametric destruction mechanics are formulated and illustrated. Senior students, magistrates and graduate students of technical universities, as well as scientific and engineering and technical workers who are interested in modern problems of strength and destruction of solid bodies, safety, survivability and resource of technical systems
