We propose an approximate semiphenomenological model of the joint process of cold plastic deformation and fracture of metals. Within the framework of this model, for 10kp, 20kp, 20G2R, and 38KhGNM steels, we show that moving dislocations overcome barriers through a force process. The formation of nascent microcracks is also realized through a force process, i.e., local stresses in the “head” of an arrested dislocation pileup attain the levels of theoretical strength. We also suggest a general algorithm of the application of the proposed model to the prediction of fracture of metals in technological processes of plastic metal working.
