Abstract
The physical concepts of fracture, which is treated as a kinetic, statistical, multistage, and multiscale process, are presented. Microscopic models for crack nucleation and growth based on the physics of defects (dislocations, disclinations, and vacancies) are examined, and the principal stages of the fracture process are discussed. In particular, attention is given to the generation of local superstresses, nucleation and growth of microcracks, nucleation of macrocracks, the structure of the plastic zone at the tip of a macrocrack, and unstable crack growth. Particular cases involving changes in loading conditions, lattice type, or dislocation structure are examined. 177 references.
