Abstract
In this paper, we calculate stress fields of an edge dislocation in finite body. Dislocation is important to think a slip of the metallic crystal in plastic deformation. Analysis of an elastic stress field of dislocation near the boundary is useful to investigate dislocation pile up and slip out to free surface. In this paper, we deal with the edge dislocation. It is one of the line defect and has a singular stress field. There is the theoretical solution of edge dislocation in infinite body, but there is not theoretical solution in finite body. In this paper, we calculate stress fields of one edge dislocation in finite body by a combination of theoretical solution of edge dislocation in infinite body and analytical solution by indirect boundary element method. Further, we try to calculate the force acting on the edge dislocation.
