“…The experiments showed that this structure had a much higher energy absorption and a steadier load carrying capacity than the single foam-filled tube under a bending condition [28]. Furthermore, for the experimental results of the cylinder tube structures under quasi-static oblique impact loading, the circular double tube had a greater energy absorption [20]. For these reasons, the double circular thin walled tubes were modified in an attempt to create the best structural model.…”

“…Reyes et al [16][17][18][19] studied square aluminium extrusion response, square tubes with and without foam, and circular tubes subjected to oblique loading, and obtained both experiment and simulation results. 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.…”

“…Furthermore, because of their good capability in energy absorption, these structures should be explored more, in order to gain an optimal design [20,28]. The aim of this current study paper is to optimize the crashing behaviour of double circular tubes under pure axial and oblique impact loadings using three different tubes, namely empty-empty double tube (EET), Foam-filled Empty Tube (FET), and Foam-Filled double Tube (FFT).…”

“…In each of the above-mentioned studies, the double circular tube could be further explored to understand the optimal design, because it has demonstrated good energy absorption capacity (Guo et al, 2011a;Li et al, 2012). In the current study, ways in which the performance of empty and foam-filled double circular tubes under axial impact loading can improve crashworthiness are discussed.…”

Fuel consumption and safety are currently key aspects in automobile design. The foam-filled thin-walled aluminium tube represents a potentially effective material for use in the automotive industry, due to its energy absorption capability and light weight. Multiobjective crashworthiness design optimization for foam-filled double cylindrical tubes is presented in this paper. The double structures are impacted by a rigid wall simulating quasi-static and dynamic loadings. The optimal parameters under consideration are the minimum peak crushing force and maximum specific energy absorption, using the non-dominated sorting genetic algorithm-II (NSGA-II) technique. Radial basis functions (RBF) and DOptimal are adopted to determine the more complex crashworthiness functional objectives. The comparison is performed by finite element analysis of the impact crashworthiness characteristics in tubes under static and dynamic loads. Finally, the optimum crashworthiness performance of empty and foam-filled double tubes is investigated and compared to the traditional single foamfilled tube. The results indicate that the foam-filled double aluminium circular tube can be recommended for crashworthy structures.

“…Some researchers were interested in tapered thin-walled rectangular tubes for their high impact energy absorption [1,2]. The liquid or foam filled inside structures had long known for their abilities to absorb and to dissipate high-velocity impact loads [3][4][5][6][7][8][9][10][11][12][13][14][15] Some of researches aimed to find effects of liquid levels filled inside structures on abilities to absorb impact energy [16,17] while other focused on controlling liquid sloshing inside structures [18] or determined vibration characteristic of liquid [19] during impact. One application of liquid filled inside structure is not only to absorb impact energy but also to add weight to the structure for minimizing its structural movement commonly found in design of vehicle barriers [20,21].…”

Abstract. Water-filled containers have long known for its structural characteristic of impact load absorption. This paper presents design of structures resisting to impact load resulting from a high-velocity tennis ball. One cubic meter water containers consisting of rectangular, cylindrical, and spherical water containers and water levels were studied for their stress distribution and deformation during maximum deformation period using finite element analysis in the ANSYS 15.0 software. The containers were modeled by using shell elements and made of elasto-plastic material of HDPE plastic. The filled water was model by using fluid elements. We found that as ball velocity increased, maximum von Mises stress increased. However, for post-yielding behavior, maximum von Mises stress approached a constant near yield stress of HDPE material. As ball velocity increased, deformation increased. When water level increased, maximum deformation decreased. For the rectangular and cylindrical containers, when the water level increased, the maximum von Mises stress increased. However, in the spherical container, as water level increased, the maximum von Mises stress was not significant change. Among three water-filled containers, the rectangular container has the highest efficiency in impact absorption, followed by the cylindrical container and the spherical container respectively.
