Aluminum foam with the property as the excellent impact absorption has been widely used recently. It is necessary to study fracture energy due to fracture toughness by the use of adhesive joint at aluminum foam. This study aims at strength evaluation about adhesive joint on aluminum foam and the fracture of bonded DCB model with this material property is analyzed by simulation. These models are designed by differing in height on the basis of British industrial and ISO standards. As the value of height at model is higher, bonded part is separated to the end. By comparing some analysis results with experimental data, these data could agree with each other. By the verification with experimental results, these all simulation results in this study can be applied on real composite structure with aluminum foam material effectively. The fracture behavior and mechanical property can also be examined by this study.
