This paper presents an extension to the normal formulation of this method to enable stress intensity factors to be solved directly at the crack edges. This is achieved by employing an enhanced edge collocation procedure. The limiting interpretation of the governing integral equations is discussed and two simple examples are presented to illustrate the application of the method.enCrack edge collocationsCrack fractureDisplacement discontinuity methodsArticleNapier, J.
