영어초록

The simulation analysis about the mechanical behavior by thickness on the compression procedure of the bonded aluminum foam is carried out in this paper. The maximum equivalent stress is increased very rapidly at three models. This stress approaches the yielding point when the compressive displacement is proceeded as much as 6mm. After yielding point, this stress approaches the maximum point. A value of this stress is about 1.0MPa. The reaction force approaches the maximum point when the compressive displacement is proceeded as much as 6mm. These reaction forces are shown to be 3000N, 5000N, 7100N respectively at the specimen thicknesses of 15, 25 and 25 mm. The maximum deformation energy is abruptly increased from the displacement of 6 mm and the compressive energy in case of the specimen thickness of 15 mm is shown to highest among three specimens when the displacement is proceeded as much as 13 mm. The experiment with the case of specimen thickness of 25mm is carried out in order to verify these analysis results. The mechanical properties of the bonded structures composed of aluminum foams can be thought to be analyzed effectively.
