On the basis of the existing fundamental solutions of displacements,further improvement ismade,and then the general fundamental solutions of both plane elastic and plane plastic problems for ortho-tropic materials are obtained.Two parameters based on material constants α_1,α_2 are used to derive the rele-vant expressions in a real variable form.Additionally,an analytical method of solving the singular integral forthe internal stresses is introduced,and the corresponding results are given.If α_1=α_1=1,all the expres-sions obtained for orthotropy can be reduced to the corresponding ones for isotmpy.Because all these expres-sions and results can be directly used for both isotropic problems and orthotmpic problems,it is convenient touse them in engineering with the boundary element method(BEM).
