| Abstract: | In.the present paper,two-dimenstional deformation problems of an anisotropic boby.with a parabolic boundary.are sysiematically analysed by using Lekhnitskii's formalism and the mapping functions method.then a special.structure-the half-infinite crack problem is studied through the obtained results.the sinular fields and the sress iniensity factors near the crack tip are also obiained. |

| Keywords: | Lekhnitskii method eigenvalue stress intensity factor |
