[2,10] Figure 9 prescribed the bulkhead distribution on the top of BPDBN tubes with k = 1/12, 1/10, and 6 at the bottom. For a BPDBN tube with k = 1/12, the distance between the first bulkhead and the column's top and between the first and second bulkhead is much lesser than the others.…”

Non-convex tubes that have superior energy absorption potential may expand and deform unstable during impact, limiting energy absorption. The bamboo node can strengthen bamboo by resisting expansion. Therefore, bulkhead proportional distribution of bionic non-convex (BPDBN) tubes, an integrator of them, may present more efficient energy absorption performance. This research proposed to investigate the effect of geometrical parameters on the crashworthiness characteristics of BPDBN tubes. The position of bulkheads was assumed to vary according to the positive proportional function primarily determined by proportional coefficient k. The dynamic response was evaluated by the initial peak force (IPF), specific energy absorption (SEA), and crush force efficiency (CFE). Multi-objective optimization method was utilized to further improve the energy absorption performance. The optimal design lowered the IPF (34.00%), increased the SEA (37.16%) and the CFE (42.95%). This paper emphasizes that optimizing the geometrical parameters and the bulkhead distance proportion can significantly improve the crashworthiness performance of BPDBN tubes.

“…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]. Venkat Chillaet al conducted compression and bending experiments on empty highpressure tubes, non-in situ aluminum foam-filled tubes, and in situ aluminum foam-filled tubes; the specific energy absorption of in situ aluminum foam-filled tubes increased by 61% and 10% compared with the empty and non-in situ aluminum foam-filled tubes, respectively [23].…”

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.
