000004675 520__ $$2eng$$aReliable computational solutions for SIF of surface cracks have been reported by many researchers such as Newman. However, all solutions have a limited range of validity for the crack depth ratio (the ratio of crack depth to member thickness is less than 0.8). For cracks grow beyond this barrier, SIF are obtained by extrapolation e.g. BS7910. Precision of this approach is still questioning. To investigate the detailed process of crack growth until breaking through occurs, solutions for SIF not available are necessary. It has been common to calculate the SIF based on the J integral. However, in the case of deep surface crack, ligament left for carrying out the J integral is very limited and leads to a questionable accuracy of SIF. Consequently, a localised approach, nodal displacement method,was adopted. All computational works were carried out based on finite element code ABAQUS in which the node displacement close to the crack tip were determined. Post-processing of these extracted displacement was then carried out to determine the desired SIF.
