In this paper,based on paper [1] and [2], bending integral expressions of the stress function and shear stresses of a cylinder with several cracks are obtained. Using the numerical method of the singular integral equations[3],it is easy for us to do the numerical calculation of the stresses and stress intensity factors, which is similar to that of paper[1].
