A study on mechanical characteristics of aluminum foam jointed by adhesive per thickness under compression.

This study aims to investigate the mechanical behaviors under compression on the specimens of aluminum foam jointed with various thicknesses by using adhesive after being clipped to the height of 100 mm, the width of 100 mm, and the thickness of 25 mm. For the study, a simulation analysis was conducted by using the commercial finite element analysis program of ANSYS, and the process to verifying the result of simulation analyses in comparison with actual experiments was implemented. According to the results of experiments, reaction forces were risen rapidly to the yield point and this force maintained with a constant value was generally observed up to the rupture although there was the minute vibration due to the irregular arrangement of internal bubble structure as the characteristics of porous material. The simulation results could be seen to be reliable while all specimen models were different in view of the time to reach the yield point. This study identifies the mechanical characteristics of aluminum foams jointed by adhesive per thickness under compression and the result is thought to make a great contribution to the follow-up studies about the real structure jointed with aluminum foam.
