“…They found that adding the aluminum foam core material had a significant effect on the energy absorption capacity of the structure. With an energy absorption contribution of 33%-45%, the foam core is an integral part of the structure [21]. Cui et al also found that the aluminum foam filling increased the flexural load capacity and limited the lateral displacement of thin-walled tubes [22].…”

Aluminum foam-filled tubes are complicated structures created by filling one or more thin-walled metal tubes with varying shapes in cross-sections with aluminum foam. We optimized the structure of aluminum foam-filled tubes using software simulation, compression, and three-point bending experiments. Filling aluminum foam not only improves the axial compressive performance and bending strength of the thin-walled metal tube but also eliminates the disadvantage of the low strength of the aluminum foam. The aluminum foam-filled single tube exhibited significant improvements in load-bearing and energy absorption, with a one-time increase in load-bearing and five times increase in energy absorption compared with an empty tube. The aluminum foam-filled single tube with a smaller diameter-to-thickness ratio has a higher load-bearing capacity. In contrast, the length-to-diameter ratio has a lower impact on load-bearing capacity. Once the filling length reaches the effective filling length, the structure can still support higher loads and effectively reduce its overall weight. The compression and bending properties in the double-tube structure filled with foam aluminum improved significantly compared with the empty tube and single-tube structure filled with aluminum foam. The total compressive energy absorption capacity in the double-tube structure filled with aluminum foam is 2.01 times that of the empty tube and 1.81 times that in the single-tube-filled structure. When the wall thickness of the filled stainless steel tube is 1.0 mm, the total bending energy absorption and the specific absorption energy of the aluminum foam-filled double tube structure are 1.5 and 2.1 times that of the corresponding aluminum foam-filled single tube, respectively.

“…The results showed the best specific mechanical energy absorbing capacity in the case of foam-filled tubes. Liu et al [30] studied the dynamic response and energy absorption ability of foam-filled tubes under lateral external blast loading. The result revealed that the introduction of the foam core was very important in the deflection and energy absorption ability of the structure.…”

Based on a modified Voronoi tessellation technique, a series of isotropic negative Poisson's ratio (NPR) Voronoi foam models were proposed via finite element method (FEM). And the proposed models were prepared by reverse modeling method. Poisson's ratio and stress-strain relationship of the proposed models were studied via FEM and experimental method. Results showed that the structure exhibited negative Poisson's ratio and isotropic behavior. With the increased of the relative density of the model, the absolute value of Poisson's ratio decreased gradually. The results of FEM and experiment showed good consistency. Then, a foam-filled structure was built by filling the proposed NPR Voronoi foam into a square tube. And its energy absorption ability was studied and compared with an isotropic chiral lattice foam-filled tube. Results showed that the energy absorp-tion ability of the proposed NPR Voronoi foam-filled structure was 11% higher than that of the isotropic NPR chiral lattice foam-filled tube with the same relative density. The research was ex-pected to be meaningful for the further research and application of the isotropic NPR foam.

“…Chen and coworkers [11] provided a complete solution of large plastic deformation of square plates under exponentially decaying pulse loading, through the combination of saturation analysis and membrane factor method. Liu and coworkers [12] experimentally and numerically studied the dynamic response and energy absorption performance of foam-filled tubes under lateral external blast loading. Bai and coworkers [13] presented a numerical model for the thermal-elastohydrodynamic lubrication of heterogeneous materials in impact motion.…”
