Recently, the weight reduction and the safety are becoming important objectives at automotive engineering, and the materials used for automotive parts are transiting from steel and iron to plastic or multi-porous materials. In this study, aluminum foam is designed with the test specimen of TDCB shape. The shear fatigue strength is evaluated by being based on static behavior analysis under mode II conditions. The study results were verified through experimentation. The length and thickness of the TDCB test specimen models were 200mm and 25mm, respectively. As for the angle of the contact interface, 3 models were modeled, at 2° intervals from 6° to 10°. Examination of the results for the three models shows that under the same fatigue load conditions, the larger the tapered angle in the TDCB models, the longer the models are able to withstand the fatigue load. Also, in this study, using the finite element method, the adhesive strength against shearing fatigue load at the TDCB bonded structures with aluminum foam can be evaluated. It is thought that use of such verified analysis results is one method through which the structural safety of actual structures can be evaluated through analysis alone, without experimentation.
