Designing materials and structures with high energy absorption and self-recoverability remains a challenge for reusable energy absorption, particularly in aerospace engineering applications (i.e., planetary landers). While the prevalent design methods of reusable energy absorbers mainly use the mechanical instability of tilted and curved beams, the limited energy absorption capabilities and low strength of tilted or curved beams limit performance improvement. In nature, Phlorodes diabolicus has evolved extreme impact resistance, in which the suture interface structure plays a key role. Herein, we propose a convex interface slide design strategy for reusability and energy absorption through friction interface, geometry, and bending elasticity, inspired by the elytra of Phlorodes diabolicus. Convex interfaces slide to achieve a more than 270% higher energy absorption capacity per unit volume than the curved beams. The convex interface slide design can be easily integrated with other structures to achieve multiple functions, such as various shapes and self-recoverability. Furthermore, we developed a theoretical model to predict the mechanical behavior and energy absorption performance. Our strategy opens up a new design space for creating reusable energy-absorbing structures.

The impact resistance of aluminum foam sandwich panels (AFS) with metallurgical bonding interfaces prepared by the powder cladding rolling method was investigated. Low-velocity impact tests were conducted by using a drop-weight impact facility to explore the dynamic mechanical behavior, deformation and damage mechanisms, and energy absorption of AFS with metallurgical bonding interfaces. The effects of variation of impact energy, panel thickness, and specimen density on the energy absorption performance of AFS were quantitatively evaluated by energy absorption indicators. The results indicate that the load-displacement curve illustrates prominent three-stage characteristics when the impact energy is 120 J containing the front panel yielding stage, the foam core’s compressive and shear failure stage, and the back panel fracture stage. The impact strength of the sandwich structure increases with increasing panel thickness and specimen density. The AFS with metallurgical bonding interfaces presents favorable energy absorption efficiency under low velocity.

“…The compression data of four aluminum foams were compared. The results showed that the energy-absorption capacity of the structure could be improved by adding an iso-density core layer and a sandwich plate under quasi-static compression conditions [14]. The energy-absorption characteristics of a new type of anti-collision material with a metal hollow-sphere structure under impact were studied by means of experiments and calculations.…”

To study the attenuation and dispersion effect of a new protective structure distribution layer constructed with a hollow particle composite material on the shock wave, a similar model field explosion test was carried out in this paper. The numerical simulation of explosion tests under different conditions was carried out by using the finite element program 3D/LS-DYNA and the test results were used for verification. The experimental results showed that under the same charge conditions, the shell-shielding layer above the distribution layer of the hollow-shell particle composite material was greatly deformed and the damage was more serious than that above the distribution layer of yellow sand, which had an obvious attenuation effect on the shock wave. Under the same charge condition, the stress peak at the bottom of the distribution layer of the empty shell particle composite material was 0.47 times that of the distribution layer of yellow sand at the same position; the stress wave rose and the pulse width increased, which had an obvious dispersion effect. The distribution layer constructed by the hollow particle composite material had no obvious overall comminution damage, which improved the secondary anti-explosion ability of the protective structure. Therefore, the distribution layer constructed with the hollow particle composite not only enhanced the energy absorption and wave elimination of the protective structure, but also improved the safety of the protective structure.
