摘    要:Based upon Stroh formalism we derive a novel and convenient scheme for determiningthe elastic fields of a two-dimensional anisotropic body with a parabolic boundary subject to two kindsof boundary conditions, which are free surface and rigid surface, respectively. The correspondingGreen's functions are found by using the conformal mapping method. When the parabolic curve de-generates into a half-infinite crack or rigid inclusion, the singular stress fields near the tip of defectsare obtained. In particular, those Green's functions for a concentrated moment M_0 applied at a pointon the parabolic curve are also studied. It is easily found that arbitrary parabolic boundary value prob-lems can be solved by using these Green's functions and associate integrals.

Abstract: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 de- generates into a half-infinite crack or rigid inclusion, the singular stress fields near the tip of defects are 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 prob- lems can be solved by using these Green's functions and associate integrals.
