An integral technique has been used to estimate opening mode stress intensity factors, K1 , for embedded rectangular and irregular planar defects subjected to uniform tension. These estimates have been confirmed by stress freezing photoelastic techniques. Also K1 estimates for rectangular defects are shown to compare well with theoretical solutions obtained by others.
