The Stress Compensation-Displacement Discontinuity Method (SC-DDM) is improved to precisely analyze the internal stresses of homogenized compressible joints, and interdependent effects of them are discussed by analyzing the joint-tip fracture upon the maximum circumferential stress criterion. A relative joint compressibility ratio is proposed to represent the compressibility of the joint. The internal stresses are represented by a central joint stress coefficient and a joint stress function, and they are formulated as a function of elastic and in-elastic displacements in the joint, which are represented by a set of central displacement coefficients and joint displacement functions. The analysis is carried out by taking an overall slide on the joint surface into consideration. Additionally comparing the compressible solution to the in-compressible one, it is discussed that the joint compressibility plays an important role to determine the critical pressure of the joint-tip fracture, along with the joint spacing.
