Summary:Moving dislocations in anisotropic piezoelectric crystals are treated. The basic equations governing the displacement and electric potential are presented, and their solutions are given by the method of Green's functions. The elastic strain and electric fields are calculated from those solutions. They are expressed entirely in terms of the dislocation-density and dislocation-flux tensors by means of the volume integrals with respect to the region where there exist dislocations. The expressions are specialized into those for the fields of uniformly moving infinite straight dislocations in a cubic anisotropic crystal. The analytical expressions for those fields are given for a screw dislocation moving on a plane of symmetry.
