“…The SIFgradient dK/da affects HAC so that the tests for crack initiation (where dK/da > 0) and crack arrest (dK/da < 0) give different values of KnAC, although the effect has the opposite signs in the special cases (see [17,18]). …”

We analyze the concept of threshold stress intensity factor K~AC and its importance for the processes of hydrogen-assisted cracking (HAC). We discuss the self-similarity of the zone near the crack tip welldescribed by the stress intensity factors K, indicate the ambiguities encountered in the determination of KHAC and the experimental parameters affecting the thresholds of hydrogen-assisted cracking parallel with K. It is shown that KnA c has the physical meaning of the lower bound of the stress-intensity factors corresponding to the initiation of hydrogen-assisted cracking (if all other conditions are arbitrary). To obtain reliable estimates of KnAc, one must impose additional restrictions on the experimental procedure of its evaluation.
