碩士 === 國立臺灣科技大學 === 機械工程系 === 102 === This study presents in-plane elasticity problems of the two bounded circular inclusions subjected to an arbitrary singularity point. Based on the technique of conformal mapping and the method of analytical continuation in conjunction with the alternating technique, both the displacements and stresses are in terms of the Muskhelishvili’s complex potentials.The image forces acting on the dislocation are calculated through the Peach-Koehler formula. The interaction between an edge dislocation and circular inclusions is also discussed for different materials and geometry in this study.And the equilibrium position and subsequent stability of the dislocation are determined and the magnitude or direction of dislocation’s movement is discussed in detail. This study calculated the image forces acting on the dislocation using MATLAB R2009b software.
