“…Recently, some novel honeycomb-based structures were proposed, such as embedded [ 12 , 13 ], tandem [ 14 , 15 , 16 ], hierarchical [ 17 ], and negative Poisson’s Ratio (NPR) [ 18 ] honeycombs. Moreover, filling tube [ 19 , 20 , 21 , 22 ] and foam [ 23 , 24 , 25 , 26 , 27 , 28 ] into honeycomb was also regarded as an efficiency method to increase the mechanical and energy-absorption performances.…”

Polylactic acid (PLA) hexagonal honeycomb structures were fabricated by using 3D-printing technology. By filling with absorbent polymethacrylimide (PMI) foam, a novel absorbent-foam-filled 3D-printed honeycomb was obtained. The in-plane (L- and W-direction) and out-of-plane (T-direction) compressive performances were studied experimentally and numerically. Due to absorbent PMI foam filling, the elastic modulus, compressive strength, energy absorption per unit volume, and energy absorption per unit mass of absorbent-foam-filled honeycomb under L-direction were increased by 296.34%, 168.75%, 505.57%, and 244.22%, respectively. Moreover, the elastic modulus, compressive strength, energy absorption per unit volume, and energy absorption per unit mass, under W-direction, also have increments of 211.65%, 179.85, 799.45%, and 413.02%, respectively. However, for out-of-plane compression, the compressive strength and energy absorption per unit volume were enhanced, but the density has also been increased; thus, it is not competitive in energy absorption per unit mass. Failure mechanism and dimension effects of absorbent-foam-filled honeycomb were also considered. The approach of absorbent foam filling made the 3D-printed honeycomb structure more competitive in electromagnetic wave stealth applications, while acting simultaneously as load-carrying structures.

“…In order to improve the mechanical properties of honeycomb structure and its energy absorption capacity, a novel design consisted of honeycomb panel filled with tubes or foam was recently developed. Numerous investigations have been carried out concerning this topic and important results have already been reached [ 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 ]. Zhang et al [ 29 ] studied the quasi-static compressive of tube-reinforced aluminum honeycomb.…”

This paper aims to investigate the crashworthiness performance degradation of a damaged 5052 aluminum honeycomb panels under in-plane uniaxial quasi-static compression and the possibility of improving it using reinforcement tubes. The in-plane crushing behaviors and energy absorption capacities of the intact, damaged, and tube-reinforced damaged panels with different damage sizes in both X1 and X2 directions are numerically simulated by using the nonlinear FE method Abaqus/Explicit, and the crashworthiness performances are compared with each other. The validation of finite element model involves comparing the obtained simulation results with theoretical and experimental ones. Very good agreement between numerical, experimental, and theoretical results is achieved. The first maximum compressive load and the mean crushing load of the different honeycomb configurations are analyzed and compared through the load–strain curves. The energy absorption capacity of the damaged and the tube-reinforced damaged panels is calculated and then compared with their corresponding intact ones. The deformation modes are explained in detail. The obtained results show that the crashworthiness performance degradation is directly proportional to the damage size as well as the insertion of reinforcement tubes considerably improves in-plane crushing resistance of damaged honeycomb panels.

“…His work has shown that these lightweight structures feature desirable properties, but also need further experimental and simulation work to complete their characterization under quasi-static and crushing load. The mechanical behavior of thin-walled multi-cell tubes combined within vertex-based hierarchical configurations has also been analyzed from a theoretical and numerical perspective [15][16]. The lateral crushing and energy absorption properties of thin-walled structures under different parameters have also been studied under quasi-static experimental and simulation tests [17][18].…”

In this work we propose a new type of thin-walled energy absorbed structure with hollow columns that possesses a design inspired by the beetle elytra. The failure mode of the bionic thin-walled structures is firstly discussed by developing a theoretical model. The energy absorption properties of these bio-inspired multi-call thin-walled structures have been then investigated using nonlinear finite element simulations. The values of the specific energy absorption and the crushing force effectiveness have been evaluated for different structures with parametrized column nested configurations. Dynamic impact simulations of multi-cell tubes with different columns nested modes, wall thickness and impact angles have been performed and the results discussed.
