Because aluminum foam is porous material, the frature property is different from that of non-porous material. This aluminum foam can be used with the joint bonded with adhesive in order to utilize the light weight to the maximum. So, the study of fracture property on bonded surface can be important. In this study, the analyses on the specimens with two kinds of configuration as DCB(Double Cantilever Beams) and TDCB(Tapered Double Cantilever Beams) aluminum foams of mode Ⅲ type bonded with adhesive are carried out and compared with each other. And the fracture properties the adhesive surfaces of the structure with bonded aluminum foams are studied as the static experiments on these verifications are done. DCB and TDCB specimens used in this study have the variable of thickness(t) as 35mm, 45mm and 55mm. As the result of this study, the range of reaction forces are 0.3 to 0.8 kN and 0.5 to 1.2 kN at DCB and TDCB specimens respectively. The results of the static experiments can also be confirmed with these similar results. These study results can be obtained by only a simulation without the special experimental procedures. The mechanical properties of the bonded structures composed of DCB and TDCB aluminum foams with mode Ⅲ type can be thought to be analyzed effectively.
