“…Porous materials such as foam aluminum have been used in the design of thin-walled tube filling because of their good light-weight energy absorption characteristics, which has important practical significance to improve its anti-compression property. Wang et al 8 carried out a comparative study on the energy absorption characteristics of the hollow thin-walled tube and the polyurethane filled thin-walled tube, verified the superior property of the filled tube, and established an equivalent mechanical model to characterize the interaction between the tube and foam. Wang et al 9 and Li et al 10 systematically studied the deformation behavior, failure mode and response characteristics of 3D printed multi-cell filled thin-walled structures under quasi-static and dynamic compression loads, and analyzed the influence of different structural parameters on the energy absorption characteristics of the filled tubes.…”

In this paper, a new type of thin-walled energy absorbing structure filled with auxetic lattice structure has been proposed. The deformation mode and mechanical responses of the new filled tube under compression load have been studied through quasi-static compression experiment and numerical simulation. A theoretical model for predicting the average compression force has been established and verified with simulation analysis. The influences of the geometrical parameters in the compression performance of the filled tube have been studied. The results show that the failure mode of the filled tube under compression load is local buckling failure. Compared with the single thin-walled tube and the lattice structure, the filled tube has better compression resistance. Through parameter analysis, it is clear that the anti-compression property of the filled tube can be significantly improved by increasing the wall thickness of the cell rod and the angle of the lower support rod, which will provide an important reference for the anti-impact optimization design of the negative Poisson’s ratio lattice filled structure.

“…Compared to polyurethane foam, metal foam, specifically aluminum foam, exhibits higher platform stress levels. With the commercial preparation process for aluminum foam gradually maturing, subsequent researchers conducted extensive studies on aluminum-foam-filled tubes with various cross sections, including square tubes [20,[23][24][25], circular tubes [26][27][28], and polygonal tubes [23,29]. Furthermore, the potential of honeycomb-filled tubular structures in energy absorption was thoroughly examined by Hussein et al [30] and Yin [31].…”

Inspired by material hybrid design, novel hybrid sandwich shells were developed by filling a corrugated cylindrical structure with aluminum foam to achieve higher energy absorption performance. The crushing behavior of the foam-filled corrugated sandwich cylindrical shells (FFCSCSs) was investigated using theoretical and numerical methods. Numerical results revealed a significant enhancement in the energy absorption of FFCSCSs under axial compression, showcasing a maximum specific energy absorption of 60 kJ/kg. The coupling strengthening effect is highly pronounced, with a maximum value of F¯c/F¯ reaching up to 40%. The mechanism underlying this phenomenon can be approached from two perspectives. Firstly, the intrusion of folds into the foam insertions allows for more effective foam compression, maximizing its energy absorption capacity. Secondly, foam causes the folds to bend upwards, intensifying the mutual compression between the folds. This coupling mechanism was further investigated with a focus on analyzing the influence of parameters such as the relative density of the foam, the wall thickness of the sandwich shell, and the material properties. Moreover, a theoretical model was developed to accurately predict the mean crushing force of the FFCSCSs. Based on this model, the influence of various variables on the crushing behavior of the structure was thoroughly investigated through parametric studies.

An improved melt foaming method is employed to fabricate composite aluminum foam tubes (CAFTs) with varying diameter ratios, achieving metallurgical bonding between the aluminum foam and aluminum tubes. Based on the structural characteristics of aluminum foam‐filled tubes and traditional numerical formula for calculating the energy absorption properties of metal foams, a new calculation formula is proposed to accurately evaluate energy absorption performance of CAFTs under axial load, enabling more precise numerical calculation of total energy absorption. Furthermore, drop weight impact tests and finite element simulations are conducted to investigate the axial impact performance and deformation mechanism of CAFTs. The influence of diameter ratio on crashworthiness and energy absorption performance is also analyzed. As the diameter ratios decrease, both the impact resistance and total energy absorption of CAFTs increase, while the degree of tube damage gradually decreases. Moreover, finite element simulation results demonstrate that metallurgical combination between aluminum foam and aluminum tubes effectively transfers stress to thin‐walled tubes with better load‐bearing performance, preventing concentrated collapse of aluminum foam core. Additionally, the presence of aluminum foam provides robust restraint against deformation or rupture in thin‐walled tubes.
