• Absolute position of plastic strain distribution maximums in linear hardening stage changes with the same velocity as loading velocity. The latter indicates that the relative position of maximums does not change in the course of plastic flow. Analysis of plastic strain distribution in the late stages of plastic flow is also important for the following reason. Some maximums of plastic strain vanish in the course of plastic flow, while other maximums become leading. The latter provides a background for the early macroscopic fracture site formation.
