A set of fatigue and fracture assessment equations had been incorporated into British Standard 7910:2013 (BS 7910:2013) to estimate the effect of misalignment for various geometric configurations containing a surface crack. In this study, extensive 3-D finite element (FE) analyses are carried out to...
