Abstract
Aluminum foam with the property of excellent impact absorption has been widely used recently. It is necessary to study fracture energy due to energy release rate by the use of adhesive joint at aluminum foam. This study aims at strength evaluation about adhesive joint on aluminum foam. Bonded DCB specimens with this material property are experimented and the fracture behavior is analyzed by simulation. These specimens 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 analysis results with experimental data, these data could agree with each other. By the confirmation 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 its property can also be examined by this study.
