摘      要：Based upon Stroh formalism we derive a novel and convenient scheme for determining the elastic fields of a two-dimensional anisotropic body with a parabolic boundary subject to two kinds of boundary conditions, which are free surface and rigid surface, respectively. The corresponding Green s functions are found by using the conformal mapping method. When the parabolic curve degenerates into a half-infinite crack or rigid inclusion, the singular stress fields near the tip of defects ark obtained. In particular, those Green s functions for a concentrated moment M(0) applied at a point on the parabolic curve are also studied. It is easily found that arbitrary parabolic boundary value problems can be solved by using these Green s functions and associate integrals.
