## Abstract Dislocations at and near the planar interface between two anisotropic media are considered. It is shown that the energy factor for a dislocation at the interface can be expressed simply in terms of the __K__βmatrices for the two media. The __K__βmatrix is defined so that __E__=(1/2)__b_
Screw dislocations near a crack penetrating through an interface were investigated. Based on the solution of homogeneous solid, we derived the stress field, stress intensity factors and crack extension forces at both crack tips, and the image force and strain energy of screw dislocations. The mechan
