Abstract
Static three-dimensional stress intensity factors of a semi-infinite plane crack are investigated in this paper. The deformations are caused by a pair of normal and tangential point forces acting on the crack faces but located away from the crack front. Cases of symmetric and anti-symmetric loadings with respect to the crack plane are both considered. Analytic solutions are obtained by the application of Fourier transforms together with the Wiener-Hopf technique. The formulation departs significantly from the Papkovich-Neuber formulation used in previous works. This alternative formulation reduces the complexity of the calculations involved and has the same potential in regard to the elastodynamic problem. Several misprints in previous works are also noted. © 1993 Kluwer Academic Publishers.
