This study extends the η-approach used in the fracture test for the typical specimens with a through-thickness crack, to the surface cracks in plate specimens in calculating the energy release rate from the area below the measured moment versus the crack-plane rotation. The energy release rate, computed from the detailed finite element models using the domain integral approach, confirms a constant ηvalue for surface cracked steel plates. Coupled with the post-test sectioning, the unloading compliance method quantifies the extended crack-front profiles ahead of the fatigue pre-cracked surface notch, using the crack-size versus the compliance relationship derived from linear-elastic finite element analyses. The fracture resistance curves thus obtained remain similar at different locations along the crack front and comparable with the fracture resistance measured using a standard side-grooved compact tension specimen at a finite crack extension. © 2013 Springer Science+Business Media Dordrecht.||Source Title:||International Journal of Fracture||URI:||http://scholarbank.nus.edu.sg/handle/10635/53999||ISSN:||03769429||DOI:||10.1007/s10704-013-9850-3|
