Aluminum foam with porous material has the excellent mechanical property of light weight and impact absorption. It is necessary to obtain the information of fracture toughness at the adhesive work by the joint method. This study is investigated by fatigue analysis with DCB(Double Cantilever Beam) specimen models to evaluate the strengths at adhesive joints on the basis of British industrial and ISO international standards. 4 kinds of specimens are modelled by changing the height of specimen and the analysis results are compared with each other. As the height of specimen becomes lower, the displacement on the y direction, load and energy release rates become higher. Through the correlation obtained by this study result, fracture behaviors are examined and mechanical properties can be understood. Aluminum foam material bonded with adhesive can applied to the real composite structure by use of this study result.
