Interfacial dislocations and cracks in anisotropic bimaterials are considered. The displacement and the stress fields due to an interfacial dislocation are obtained in a real and simple form. Explicit solutions to the traction along the interface and the crack opening displacement for a Griffith interface crack are derived. Possible definitions of stress intensity factors are given which reduce to the classical definition for a crack in a homogeneous medium. It is found that a planar interface between dissimilar anisotropic solids is completely characterized by no more than 9 independent parameters. Some invariant properties of the dislocation and crack solutions under coordinate transformation are also discussed.

## By using a thermodynamic approach, the image force of the dislocation due to the semiinfinite crack in an infinite medium has been completed. If the influence of all the other force can be neglected, the screw dislocation subjected to the crack will approach the crack surface along the directio
