摘要：
In the paper the values of the Q-stress determined for various elastic-plastic materials for single edge notched plates in tension (SEN(T)) presented. Used in the paper specimens, are the basic structural elements, which can be used to idealizing real construction, based on FITNET procedure. The influence of the yield strength, the work-hardening exponent and the crack length on the Q-parameter was tested. The numerical results were approximated by the closed form formulas. All obtained results may be a handy catalogue of the J-Q curves, which may be useful in engineering practice.
