The critical length aIcof amode I crack that corresponds to a vanishing of the influence of the notch stress concentration can be approximately expressedby aformulareported by Lefort. This study aimedtogeneralize his approach to shear mode cracks by finding a criterion for a statistical compatibility of formulae for critical lengthsof cracks. It revealed that the Lefort ́s formula describes the critical crack length aIcatwhich the relative level of the notch effect on the modeI SIF is less than 1%. Based on this criterion, a mathematically similar formula for the critical length aIIIcwas found. A part of this study wasalso a development of a transformation procedure suitable for fitting the obtained SIF data by simple analytical formulae and for clear related illustrative plots of results.
