heal.abstract	The rate of introduction of new or quasi-new criteria of fracture is steadily increasing with time. However, the possibilities of combining sound physical principles together with simple notions of realistic concepts in mechanics, in conformity with the existing experimental evidence, are rapidly exhausted. Then, newly enlightened authors make recourse to either unrealistic conceptions or to camouflaged variations of already existing and proven criteria by picking up favorable properties from different criteria and combining them to a new entity. Little care has however been devoted for studying the conformity of the so-called new criteria with physical laws. In this paper some such examples were discussed and their weaknesses were indicated with the aim to warn imminent attempters to at least give some thought about the conformity of their finding with at least the basic laws of physics and mechanics. © 1989.	en
