Abstract

A basic procedure is given tor converting a pair of coupled two-dimensional integral equations relevant to mixed boundary value problems with annular type regions to two non-coupled integral equations. The procedure utilizes fundamental solutions to the corresponding internal and external problems in order to separate the coupled equations and write their solution in series form. The method is first applied to axisymmetric shear loading of an annular crack in a homogeneous transversely isotropic material (where the crack plane is parallel to the plane of isotropy) and to uniform tensile loading of an annular crack in a homogeneous isotropic material. Stress intensity factors are compared with previous analysis to test the accuracy of the solution. New results for stress intensity factors are given for the arbitrary normal loading of an annular crack in an inhomogeneous isotropic medium.
