0.02 (mm/mm). The ductile fracture of specimen occurs in aria where level of plastic strain was high, higher than 1.0 (mm/mm). Whereas in this area the level of stress significantly decreases. Qualitatively similar stress relationships before the crack tip were obtained during tests ferritic steel of 13HMF (Neimitz et al (2010), Dzioba et al (2010)). In these testing has been shown that the maximum stress is at a certain distance from the tip of the crack and moves away from it as the load increases.
