A B S T R A C T Crotch corner zones are of considerable concern in investigating the margin of safety against brittle fracture for tee intersections of nozzles with vessels and branch pipes with run pipes. This requires an estimate of stress intensity factor, i.e. K-factor for either postulated or d
