In this study, we deal with an elastic problem for a nonhomogeneous medium with an external crack. It is assumed that the nonhomogeneous material property of shear modulus of elasticity G varies with the axial coordinate z according to the power product form. As an analytical model, we consider a nonhomogeneous infinite body with an external crack subject to a loading on the crack surface. The displacement and stress distributions are analyzed using the fundamental equations system proposed in the previous paper and stress intensity factor at the crack tip is evaluated theoretically. And the influence of this nonhomogeneous material constant affected on the displacement, stress distribution and stress intensity factor is discussed by the results of numerical analysis.
