摘要：
The surface dislocation model is used to obtain a method of evaluating the non-local stresses of screw dislocation in a bi-medium. The exact solutions of non-local stresses of screw dislocation are given for two particular cases. All classical singularities are eliminated. Estimates are provided for the critical shear which will produce a single dislocation and for the maximum force on the screw dislocation due to the existing interface. © 1990 IOP Publishing Ltd.
