Abstract: | The Bueckner work conjugate integrals are studied for cracks in anisotropic elastic solids. The difficulties in separating
Lekhnitskii's two complex arguments involved in the integrals are overcome and explicit functional representations of the
integrals are given for several typical cases. It is found that the pseudoorthogonal property of the eigenfunction expansion
forms presented previously for isotropic cases, isotropic bimaterials, and orthotropic cases, are proved to be also valid
in the present case of anisotropic material. Finally, Some useful path-independent integrals and weight functions are proposed.
