000014196 520__ $$2eng$$aThe effect of core spreading of interface dislocation arrays on the elastic field and related properties is explored in this paper. Employing the Green’s fimction for a single compact dislocation, we derived the expressions for the elastic fields associated with core- spreading dislocation arrays in multilayer anisotropic materials. It is found that core spreading would significantly reduce stress/strain concentration of the dislocation at the interface. The accuracy of the results is validated by the continuity of traction across the interfaces. Numerical results show that: (1) after core spreading, the stress singularity of the dislocation with condensed core is eliminated and the stress intensity near the cores region is reduced; (2) the region influenced by the dislocations is expanded for the core spreading model. Besides, Peach-Kohler Force with respect to the distance between two adjacent dislocations is analyzed, which may influence the strength of the multilayer material.
