Mode Ⅲ 형을 가진 TDCB 알루미늄 폼에 대한 정적 파괴 거동

Abstract

An aluminum foam is the super light metal which can be adjusted with the adhesive by using the joint method. In this study, the tapered double cantilever beams(TDCB) with the type of mode Ⅲ are manufactured with aluminum foam. The fracture toughness at the joint of the structure bonded with only a adhesive can be obtained. The static analyses are carried out and verified the results by the experiment. As the results of static analyses, the reaction forces ranged from 0.30 to 0.41 kN at all specimens are shown when the forced displacements are proceeded as much as 8 to 9 mm. The tapered double cantilever specimen for mode Ⅲ with the thickness of 55 mm is carried out by the static experiment representatively to verify the analysis results. As the results of analyses and experiments are compared with each other, there is a little bit of difference between these results. So, the simulation results of this study can be thought to be confirmed. It is thought that even the only analysis data omitting the extra experimental procedure can be verified in order to use the data practically. Through the result of this study, the mechanical properties at TDCB specimens with the type of mode Ⅲ can be understood.
