“…However, aluminum foam can be damaged easily when used without sufficient research. If it is used for mechanical structures, it can also cause damage and destruction or even casualties [1][2][3][4]. Therefore, this paper investigates the characteristic of junction structure for closed-cell type with aluminum foam, which is generally used as a shock absorber.…”

This paper studies the characteristics of junction structure of closed-cell type aluminum foam, which is generally used as a shock absorber. TDCB specimens were designed for mode III type with thickness as a variable and performed a fatigue experiment on them by thickness. As the result, the load value of all specimens peaks under 0 to 25 cycles and decreases as the cycles increase. As the specimen thickens by 10 mm, the maximum load value is 1.2 times. When the thickness increases by 20 mm, the maximum value increases by 1.5 times. This study result can be utilized by investigating the mechanical characteristics of TDCB specimens for mode III type under fatigue loading conditions systematically and efficiently.

“…To study the mode I type crack propagation as well as the value of the fracture toughness including a delamination of composite materials along the bonded boundary, the testing method using the double cantilever beam (DCB) specimen was employed. This method has been revised and developed as a standard testing procedure for the fracture behavior of the composite materials [2][3]. In the present study, the DCB specimen made of aluminum foam was prepared for the fatigue testing with reference to ISO standard [4] and British Standard [5].…”

This study aims to investigate double cantilever beam specimen with aluminum foam bonded by spray adhesive to investigate the fracture strength of the adhesive joint experimentally. The fracture energy at opening mode is calculated by the formulae of British Engineering Standard (BS 7991) and International Standard (ISO 11343). For the static experiment, four types of specimens with the heights (h) of 25 mm, 30 mm, 35 mm and 40 mm are manufactured and the experimental results are compared with each other. As the height becomes greater, the fracture energy becomes higher. After the length of crack reaches 150 mm, the fracture energy of the specimen (h=35 mm) is greater than that of the specimen (h=40 mm). Fatigue test is also performed with DCB test specimen. As the height decreases, the fracture energy becomes higher. By the result obtained from this study, aluminum foam with adhesive joint can be applied to actual composite structure and its fracture property can possibly be anticipated.
