As a part of light weight, the adhesive has been applied to joint the mechanical structure. The porous material is used with aluminum foam in case of the structure bonded with only adhesive. In order to confirm the durability, it is necessary to investigate the fracture toughness at the bonded joint. So, the fracture property at joint interface of aluminum foam different from the non-porous material becomes especially important. In this study, the static facture analysis was carried out with DCB specimen bonded with adhesive as the loading type of mode Ⅲ. The thicknesses of specimens are 35, 45 and 55 mm. When the forced displacements 5 mm applied on the specimen proceed at specimen thicknesses of 35, 45 and 55 mm, the maximum stresses is shown to be happened at the range from 3.3 MPa to 3.6 MPa. The maximum equivalent stress happened at the specimen thickness of 35mm becomes highest among four kinds of specimens. The static experiment is carried on in order to verify these analyses representatively. As the experimental data become similar with the simulation data, it is thought that these analysis data can be applied at analyzing them into the adhesive joint of real porous material.
