The analytical solution was obtained using the conformal mapping and the theorem of analytical continuation. It has been shown that the elastic field depends on the shear moduli of individual phase, the geometric parameters of the system, and the position and relative slip of the screw dislocation. The specific cases, that two circular cylindrical inclusions are tangent to each other and the screw dislocation is located in inclusions, were considered. The numerical results were illustrated to show the interaction between the dislocation and two circular cylindrical inclusions. (Edited author abstract) 13 Refs.展开更多
