“…This structure has been widely used in aviation [6], and architecture applications and has played an important role in earthquake, flood and other natural disaster emergency projects, such as emergency bridge construction and improvised buildings for disaster victims and the military. Accordingly, the mechanical properties of the honeycomb structure and its applications have recently been the focus of numerous studies [7][8][9][10][11][12][13][14]. Many studies have been conducted on the development and mechanical properties of honeycomb structures, with promising results using experimental and theoretical methods.…”

In this study, the flexural properties of fully integrated honeycomb plates (FIHPs) were analyzed using experimental methods and finite element analyses. The effects of the perforated surface on the flexural properties of FIHPs were investigated by analyzing the flexural failure patterns and load-deformation curves of the FIHPs. The direction of the perforated surface has a significant influence on the flexural strength, and the structure exhibits different destruction patterns depending on the orientation. The experimental results indicate that although destruction occurs in the lower skin regardless of whether the perforated surface is up or down, the strength of the material of FIHPs can be optimized if the perforated surface faces upward because the chopped basalt fiber-reinforced epoxy resin composite material is strong in compression and weak in tension. A submodel of a thin honeycomb plate containing holes was developed to discuss these issues in detail. The analysis results suggest that the stress concentration around the hole is distinct and that cracks initially appear in this high-stress area. This paper provides some conclusions to support the better use of biological structures, and it offers some important theoretical support for the application of FIHPs in natural disaster emergency projects.

“…More recently, there has been increasing interest in creating materials whose mechanical properties are largely determined by their cellular architecture rather than their chemical composition, i.e., the so-called metamaterials101112131415161718192021. Furthermore, metamaterials that are hierarchically constructed have been reported to exhibit exceptional mechanical properties such as high strength, enhanced toughness and reversible extensibility6922232425262728. Among the metamaterials, auxetic materials, which exhibit negative Poisson’s ratio (NPR), have been studied extensively61011282930.…”

In this paper we propose a general method for creating a new type of hierarchical structures at any level in both 2D and 3D. A simple rule based on a rotate-and-mirror procedure is introduced to achieve multi-level hierarchies. These new hierarchical structures have remarkably few degrees of freedom compared to existing designs by other methods. More importantly, these structures exhibit synchronized motions during opening or closure, resulting in uniform and easily-controllable deformations. Furthermore, a simple analytical formula is found which can be used to avoid collision of units of the structure during the closing process. The novel design concept is verified by mathematical analyses, computational simulations and physical experiments.

“…Through hierarchical topology, structures usually get ultralight and possess greater anti-buckling ability [5] and more excellent energy absorption [6][7][8][9]. Research group of Fan et al [6][7][8][9] have made various hierarchical lattice composite structures and revealed their priority in SEA. Sun.…”
