.... A comparison is also made between J-R curves obtained using the single specimen normalization method and the “Basic” or multispecimen procedure. A limited study of the effects of side grooving on the crack extension and on the resulting J-R curves is included here. J -integral elastic-plastic...

..., and crack length and between direct-current potential drop and crack length have been analytically evaluated for the proposed specimen geometry. An appropriate side-groove depth that avoided crack deviation from the intended plane of extension was determined experimentally, and an analytical expression...

... A test program was conducted to determine the effects of specimen thickness variations, side grooves, and crack length variations on the deformation and ductile fracture of A533-B, Cl-1 steel at 93°C. The crack extensions were estimated using the correlation between elastic compliance and crack...
