Abstract

Quantum fracture mechanics (QFM) is proposed by the author as a purely theoretical alternative of the generally accepted experimental-theoretical approach to fracture physics. The main concepts of theory and formulation of several main problems are examined. Using QFM to solve a problem of the initiation of cracks and dislocations makes it possible to predict the brittle-plastic nature of a specific crystal. Analytical and numerical results of calculations carried out using this theory are represented, including subcritical crack growth in a homogeneous lattice and intergranular layers: in loading and unloading, under stationary loading in creep conditions and in cyclic loading in fatigue conditions.
