Fig. 7 and Fig. 8 shows numerical results of the spatial distribution of y p component in the cross-sectional area perpendicular to the loading direction at the different times of evolution and defect density along the line characterizing distance to the notch in the plane with the maximum normal stress . It can be seen that when y 0    and TN/ 2 l L  there is no equilibrium defect concentration and the dissipative structure is localized on the spatial scale that is equal to the half of the critical distance.
