Hierarchical structures have been viewed as promising candidates to offer superior performance compared to regular structures. In this study, six hierarchical honeycombs are constructed by replacing each joint of regular hexagonal and square honeycombs in three different ways. Numerical simulations are performed to study the out-of-plane dynamic crushing behavior and energy absorption performance of these hierarchical honeycombs. The results show that the three ways of introducing structural hierarchy can enhance the plateau stress, crash load efficiency, and specific energy absorption of regular honeycombs. Moreover, hierarchical honeycomb constructed by replacing each joint of regular hexagonal honeycomb with a smaller circle has the highest energy absorption capacity. In addition, the optimal configurations for different hierarchical honeycombs are presented, and the region of optimal structural parameter for these hierarchical honeycombs is determined, which are useful for the selection and design of hierarchical honeycomb configuration with desirable energy absorption performance.

This paper is majorly discussing the impact resistance of hierarchical lightweight lattice structure. Firstly, the unit cells of hierarchical pyramidal lattice structure and traditional single-stage hollow pyramidal lattice structure are designed. At the same time, the concept of relative density is introduced to better demonstrate the impact resistance of hierarchical structure. In this paper, ABAQUS/Explicit software is used to simulate the drop hammer impact simulation of hierarchical structure and hollow structure. The result shows that the impact resistance of hierarchical structure is better than hollow structure. Meanwhile, the samples are prepared by 3D printing, and then quasi-static compression experiment and drop hammer impact experiment are carried out. It is concluded that the bearing and impact resistance performance of the hierarchical structure has obvious improvement than the hollow structure under both quasi-static compression and low-speed drop hammer impact.

“…There has been some works in field of TPC, but it is still in the initial stage [20][21][22][23][24]. Chen et al [25][26][27] fabricated thermoplastic corrugated sandwich structures and conducted a series of studies on their quasi-static compression performance. At present, majority of studies mainly focus on the quasi-static mechanical properties of TPC sandwich structures, while the research on their dynamic properties is relatively lacking.…”

Composite corrugated sandwich structures have a wide range of applications in aerospace field, and the loss of structural load carrying capacity due to low-velocity impact damage has become one of the main threats in practical applications. In this study, the impact resistance of corrugated sandwich panels prepared from thermoplastic composites (TPC) under low-velocity impact loading was investigated. Through a series of drop-weight experiments and finite element simulations, the impact response process and damage morphology of the thermoplastic composite sandwich panels were obtained, and the effects of different impact energy and different core arrangements on the energy absorption performance of the structure were explored. Finally, a parametric analysis of the perpendicularly-arranged double-layered corrugated sandwich panel was carried out. The results show that thermoplastic composite sandwich panels exhibit an overall collapse response rather than localised damage, and the structure maintains good integrity and stability. The perpendicularly-arranged sandwich panels rely on the orthogonal configuration characteristics to provide optimum impact load carrying capacity, their impact resistance can be further improved by increasing the thickness of top face-sheet and reducing the thickness of the middle face-sheet at the same time. This provides a basis for promoting the application of TPC in engineering and the design of sandwich structures.
