In the course of the work, the classical theory of the generation and propagation of ductile fracture was improved by analyzing the parameters of the corresponding structural state. The proposed concepts take into account the effects of plastic deformation on the relevant stages of destruction, namely: crack initiation (energy aspects of micropore nucleation); slow crack growth (plastic deformation of structural components); fast crack growth (simultaneous action of two mechanisms - viscous and quasi-brittle).
