磁电弹双材料中三维位错形成的耦合场分析
The coupled elastic,electric and magnetic fields produced by an arbitrary shapedthree-dimensional(3D) dislocation loop in general anisotropic magneto-electro-elastic (MEE)bimaterials are derived. First we develop line-integral expressions for the fields induced by ageneral dislocation loop. Then, wedislocation segment. As numericalobtained analytical solution for the fields due to a straight examples, the fields induced by a quadrate dislocation loop in MEE bimaterials are studied. Our numerical results show the coupling effects among different fields, and various interesting features associated with dislocations and interfaces.
