“…For example, wing veins in the dragonfly have a tubular sandwich microstructure (18). It is also reported that the elytra of beetles are constructed with honeycomb-like sandwich structures (19). Besides the structural reinforcement property, tape spring veins have three unique properties enabling wing folding/unfolding in ladybird beetles.…”

Ladybird beetles are high-mobility insects and explore broad areas by switching between walking and flying. Their excellent wing transformation systems enabling this lifestyle are expected to provide large potential for engineering applications. However, the mechanism behind the folding of their hindwings remains unclear. The reason is that ladybird beetles close the elytra ahead of wing folding, preventing the observation of detailed processes occurring under the elytra. In the present study, artificial transparent elytra were transplanted on living ladybird beetles, thereby enabling us to observe the detailed wing-folding processes. The result revealed that in addition to the abdominal movements mentioned in previous studies, the edge and ventral surface of the elytra, as well as characteristic shaped veins, play important roles in wing folding. The structures of the wing frames enabling this folding process and detailed 3D shape of the hindwing were investigated using microcomputed tomography. The results showed that the tape spring-like elastic frame plays an important role in the wing transformation mechanism. Compared with other beetles, hindwings in ladybird beetles are characterized by two seemingly incompatible properties: (i) the wing rigidity with relatively thick veins and (ii) the compactness in stored shapes with complex crease patterns. The detailed wing-folding process revealed in this study is expected to facilitate understanding of the naturally optimized system in this excellent deployable structure.

“…Motivated by the high strength and minimal weight of beetle forewings, as required for defense and flight, we previously investigated their three-dimensional structures and mechanical properties [21][22][23]. These investigations led to a new type of lightweight bio-inspired composite consisting of a fully integrated honeycomb structure with fiber-reinforced trabeculae at the corners of the honeycomb cores.…”

“…Chen et al reported that only the forewings of beetles are fully integrated honeycomb panels and noted that the honeycomb itself is only the core structure of honeycomb panels and not a panel structure [5,6,7,8]. Compared to core-only honeycomb panels in nature, bionic integrated honeycomb panels have the advantages of a single-process formation, good anti-compressive and anti-bending performance, and overall integrity [7,8,9,10,11]. Research studies have developed a practical and effective method for overcoming the easy detachment of the honeycomb core from the face sheets of traditional honeycomb panels and have resulted in new types of honeycomb panels with unique mechanical properties.…”

To solve the problem of critical buckling in the structural analysis and design of the new long-span hollow core roof architecture proposed in this paper (referred to as a “honeycomb panel structural system” (HSSS)), lateral compression tests and finite element analyses were employed in this study to examine the lateral compressive buckling performance of this new type of honeycomb panel with different length-to-thickness ratios. The results led to two main conclusions: (1) Under the experimental conditions that were used, honeycomb panels with the same planar dimensions but different thicknesses had the same compressive stiffness immediately before buckling, while the lateral compressive buckling load-bearing capacity initially increased rapidly with an increasing honeycomb core thickness and then approached the same limiting value; (2) The compressive stiffnesses of test pieces with the same thickness but different lengths were different, while the maximum lateral compressive buckling loads were very similar. Overall instability failure is prone to occur in long and flexible honeycomb panels. In addition, the errors between the lateral compressive buckling loads from the experiment and the finite element simulations are within 6%, which demonstrates the effectiveness of the nonlinear finite element analysis and provides a theoretical basis for future analysis and design for this new type of spatial structure.
