Further resuhs given in the present paper confnm that shallow cracks have larger crack tip opening disp~a~en~ at initiation than deep cracks. This difference in behaviour is shown to be principally caused by the different hydrostatic stresses existing at the tips of shallow and deep cracks. A new me
Critical values of the crack-tip-opening displacement, COD,, are determined on CIIspecimens having different thicknesses and ligament lengths. COD, is determined using the method of stereophotogrammetry with the scanning-electron microscope. The in&nce of specimen geometry on CODi is studied. Criter
