✦ Synopsis

The crack tip constraints 111' and m, in the KCTOD relationships and the K-R (plastic zone) relationship respectively have been evaluated and compared as a function of specimen thickness, a/w ratio and the loading geometry (namely SEN tension, SEN bending and the CT geometry). The interrelation between m' and m, has also been discussed. The effect of constraints on the crack initiation toughness has been studied and results have been discussed for a structural steel.
