Opis:: In the paper, numerical verification and catalogue of the numerical solutions based on Modify Boundary Layer Approach to determine the relationship between Q-stress and T-stress are presented. Based on the method proposed by Larsson and Carlsson, the Q-stress value are calculated for some elastic-plastic materials for different value of T-stress and external load expressed by J-integral. The influence of the external load, T-stress value and material properties on Q-stress value were tested. Such catalogue may be useful during solving the engineering problems, especially while is needed to determine real fracture toughness with including the geometric constraints, what was proposed in FITNET procedures.

Opis:: The paper contains comparing calculations of the stress fields in an elastic plate with notch along the arc of a circle, ellipse or parabola obtained by analytic method based on complex Kolosov-Muskhelishvili potentials and by numerical variation-difference method. These fields differ by no more than 2%, which, in particular, indicates the reliability of such numerical implementation. This discrepancy can be explained by the fact that in the analytical solution domain is unbounded, while the numerical calculation was carried out, obviously, for a finite field. The given stresses at the top of the notch along the arc of an ellipse or a parabola significantly increase with increasing of the relative depth of the notch (while increasing its depth or decreasing width).
