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.
