“…In addition, Li et al [20] carried out deformation and energy absorption testing, using the experiment results for aluminium foam circular tubes, subjected to an oblique quasi-static loading. For tapered thin-walled rectangular tubes, Nagel and Thambiratnam [21][22][23] showed that this structure had more advantages than straight tubes under an oblique impact. In other types of structure, Ahmad et al [24] also investigated the benefits of using foam-filled conical tubes under an oblique impact.…”

“…Furthermore, the lobes are formed by compression-lipped in bending mode. Some structures have the same under oblique impact such as square tube (Reyes et al 2002), rectangular tube (Nagel and Thambiratnam 2006) and conical tube (Ahmad et al, 2010). Figure 6 show the effect of tube wall thickness and angle of loading are assessed to determine the mean crushing force from progressive collapse to bending collapse of tube.…”

Finite element analysis and optimization design carry out for the quasi static responses of foam-filled double circular tube is presented in this paper. In the investigation of the crashworthiness capability, some aspects were considered for variations in geometry parameters of tubes and the loading condition to investigate the crashworthiness capability. Empty, foam-filled, and full foam-filled doublé tubes of thin walled structures were observed subjected to oblique impact (0˚ -40˚). The numerical solution was used to determine the crashworthiness parameters. In addition, NSGA II and Radial Basis Function were used to optimize the crashworthiness capability of tubes. In conclution, the crash performaces of foam-filled double tube is better than the other structures in this work. The outcome that expected is the new design information of various kinds of cylindrical tubes for energy absorber application.

The behavior of foam-filled thin-walled aluminum tube under impact was investigated focusing on different crashworthiness parameter. The diameter to thickness of tube ranging between 26.5 and 200 were filled with polyurethane foam density from 100250 kg·m ¹3. The specimens were crushed by a drop hammer. The result from finite element simulation and experiment was compared and good agreement was achieved. The simulation was also used to conduct further investigation on tube with higher diameter to thickness ratio. It was found that by filling foam, the tubes change their collapse modes from asymmetric mode to axisymmetric mode. Also, the energy absorption can be enhanced by filling tube with higher foam density. The impact energy was found to be managed more efficient in foam filled tube as the load efficiency is higher in higher density foam-filled tube. However, the specific energy absorption of foam-filled tube is getting lower in higher density foam. This paper provides experimental and numerical data as well as discussion in various aspects of crashworthiness.
