Abstract
In this study, the fracture property is investigated with the configuration of tapered double cantilever beam different from that of the existing double cantilever beam. Aluminum TDCB (Tapered Double Cantilever Beam) specimens of mode III-type are bonded by an adhesive. The specimens had thicknesses as a variable which were 35 mm, 45 mm, and 55 mm, respectively. In the case of the specimen with a thickness of 35 mm, the maximum reaction force was shown to be about 0.4 kN when the forced displacement had progressed by about 8 mm, while the maximum reaction force of about 0.45 kN occurred in case of the specimen with a thickness of 45 mm when the forced displacement proceeded by about 7 mm, and the maximum reaction force of about 0.54kN occurred in case of the specimen with a thickness of 55mm when the forced displacement proceeded by about 7 mm. In addition, the static fracture analysis was performed for its verification by using the finite element analysis of ANSYS program, where it was affirmed that the experimental results and the simulation analysis results were shown to be similar. Based on this observation, it is considered that the simulation analysis data could be applied to the bonded interfaces of actual porous materials.
