Aluminum foam fits with the light material and has the superior physical and mechanical properties. On the other hand, if the aluminum foam is used arbitrarily without the study procedure, the user can be anxious about the damage of the mechanical structure applied with aluminum foam. By taking notice of this point, the aluminum foam specimens with the type of mode Ⅲ by thickness are designed and the analysis of fatigue fracture is carried out with ANSYS program. By this analysis result, the maximum load tends to increase as the thickness of spcimen increases. The experiment of fatigue fracture is carried out as this verification and the experimental data are shown to approach simulation data. Therefore, the simulation result data of this study are thought to be applied to the real structural design of aluminum foam. And the mechanical property of TDCB specimen with the type of mode Ⅲ under the fatigue loading condition is estimated to be analyzed systematically and effectively.
