　　The extended boundary element method(XBEM)is proposed to determine the singular stress field of the V-notched structures with local plastic deformation near notch tip in this paper.Firstly,the V-notched structure is divided into two parts,a small region around the V-notch tip and the remaining structure without the small region.Consider that the small region around the V-notch tip yields the plastic deformation due to the stress concentration.
