In this paper, the singular stress field around a crack meeting a bimaterial interface is analyzed. A uniform expression is presented for the singular field. The intensity of the singular stress field is defined in terms of two real constants KI and KII. By using the body force method, KI and KII are calculated. In the numerical analysis, the singularities of stress field are characterized by introducing the proper basic density functions of body force doublets. The use of the basic density functions enables one to obtain accurate solutions.
