Based on the conservation law of elasticity, a set of traction boundary integral equations have been developed. By using the non-hyper-singular traction boundary integral equations, this paper formulated the corresponding equations for 3D finite cracked bodies. Numerical algorithm for general 3D problems and a semi-analytical method for axisymmetric problems are presented. The results obtained by the proposed method are compared with the existed solutions. It is found the present method is very accurate and efficient.
