Interface Crack Tip Stress Field of Anisotropic and Orthotropic Bimaterial

The A-type case of interface crack problems of anisotropic and orthotropic bimaterial are discussed,and the mechanical model and stress function are presented. The correspondingⅠ-type interface crack tip stress field and displacement field have been obtained. As a test,when the included angle φ of anisotropic material parameters is zero,the anisotropic material will be transformed into orthotropic material. With substitution of the stress field and the displacement field,the validation results are consistent with the references.
