Application of cartwright and Rooke's K-Calibration procedure to a service problem (IM-FM-074)

Cartwright and Rooke have proposed a method for the determination of stress-intensity factors by the super-position of K-values for geometrically simpler situations for which K-calibrations are already available. The theory underlying the method is exemplified in Figs. 1 & 2. Consider first case A (Fig. 1). A crack exists...
