In this paper the values of the maximum opening stress and its distance from crack tip determined for various elastic–plastic materials for single edge notched specimens in bending (SEN(B)) are presented. The influence of the yield strength, the work-hardening exponent and the crack length on the maximum opening stress was tested. The numerical results were approximated by the closed form formulas...
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...
