“…Energy-absorbing structures play a critical role in aerospace, [1,2] railroads, [3,4] and construction [5,6] by facilitating the orderly and controlled dissipation of kinetic energy during impacts, thereby reducing injuries to passengers. With increasing demands for passenger safety and the performance of key materials, energy-absorbing materials like honeycomb structures, [7][8][9][10] composite structures, [11][12][13][14] sandwich structures, [15][16][17][18] and new lattice designs [19][20][21][22] are widely employed due to their outstanding energy-absorption properties, mechanical strength, and crashworthiness. Honeycomb materials, in particular, are characterized by their low density, low stiffness, excellent thermal insulation, and energy absorption (EA) capabilities, along with well-established processing techniques.…”

This study extensively characterizes the out‐of‐plane stiffness and energy harvesting capabilities of a newly proposed anti‐trichiral hierarchical auxetic honeycomb structure, both mechanically and deformationally. By introducing a design concept based on the anti‐trichiral honeycomb (ATCH), a structure with superior out‐of‐plane load‐carrying capacity and excellent auxeticity is achieved. To validate the finite element model, compression simulations are conducted. Comparative investigations into the morphing characteristics and energy harvesting performance between the novel structure and the ATCH are performed. Additionally, the influence of various parameters on the comprehensive performance of the novel auxetic structure is explored. It has been found that the angle φ is most sensitive to the auxetic properties, while the ratio k significantly impacts energy absorption. This research advances the design of novel auxetic structures for potential applications in protective engineering.
