structure and mechanical properties of beetle wings: a review

The family including. Examples of this span from dislocations, grain boundaries, and precipitates in metallurgy to voids and imperfect interfaces in natural composites. sex recognition, and also for camouflage and mimicry. (1) The elytra has a lightweight border frame structure and has an optimal design, which includes variable cross-sections suitable for different positions and enables the required moment of inertia needed for flight. This review introduces two major aspects of nanotechnology as an innovative and challenging theranostic strategy or solution: (i) the most intriguing (bare and functionalized) nanomaterials with their respective advantages and drawbacks; (ii) the current and promising multifunctional “smart” nanodevices. Their inner structure helps to provide light mass and high strength. integrated honeycomb structure with fiber-reinforced trabeculae at the corners of the honeycomb cores [Chen et al., 2005; Chen et al., 2012]. The sum of concentrations of all elements in the orange regions of the elytra was 9% lower than in the black ones. This paper presents the experimental study and numerical simulation on the influence of the constructional damping of mounting on the beetle wing-based frame vibrations. shown to be self-cleaning, providing lower adhesion with soil. Mechanical fastening, conventional welding and adhesive bonding are Classification of some beetle which have been investigated for structure and mechanical properties, The water-capturing surface of the fused elytra of the desert beetle Stenocara sp. The, distributions of species investigated mostly belong to the family, much attention. Segment: E, elytra; H, hind wing; S, Setae. When at rest, the wings are held over the back in most beetles, which may, involve longitudinal folding of the wing membrane and some-, times also transverse folding. from 0.15–0.48 GPa and 4.34–8.16 GPa, respectively. reflectors: structural color of Manuka beetles and titania coatings. The pivot of the scissors-like movement of RA and MP1+2 is the medial bridge (e, in. which resembles a crystal lattice (Fig. Chapman, 1982) and will not be discussed further in this paper. The folding/unfolding mechanisms of beetle hind wings may. 5a and 5b show the models of the trabecula. These can enable complex failure modes and balance competing mechanical properties. sjy@jlu.edu.cn, b (c) Directionality of microtrichia in the thoracic dorso-medial field. The structural and mechanical properties in living organisms may improve the understanding of natural solutions and advance the design of novel artificial materials. Also, inspired by the design of the, elytron surface of this beetle, different methods can be used to, fabricate alternative superhydrophobic and superhydrophilic, tion structures were implemented on the surfaces of a series of, superhydrophobic/hydrophilic patterns by employing a micro-. Torrincolidae, Hyddroscaphiidae, and Sphaeriusidae. The elytra are rigid. Aksay, American Institute of Physics, 1995. This study presents a biomimetic optical material based on polymeric inverse opals that respond to enzyme activity. The characteristics of folding and unfolding of wings were analyzed. characteristic also helps dung beetles to reduce soil adhesion. habits and requirements of living activities.

In: 28th Symposium Composites of Japan the Society of Materials Science, 1999. The schematic in Fig. In this paper, the morphological and histological structure of the wings of two species of beetles, Tribolium castaneum and Tribolium confusum, has been investigated using scanning electron microscopy (SEM). Bioinspiration opens up new directions in materials science, nanotechnology, photonics and several other fields of science, Since the beetle (Coleoptera, an order of, insect) is the most diverse insect order (comprising about 400, species) and exhibits some remarkable features, its wings have, Beetle wings are composed of a forewing (also known as, elytron) and a hind wing; see Fig. Two types of artificial wings driven by a shape memory alloy with 5V, 1.5A power supplyweredeveloped.Truongetal. With modern methods of measurement it is possible to enter the structure – function relationship much more deeply, even down to a molecular level, which was not possible two and a half decades ago. AA, Analis Anterior; AP, Analis Posterior; CuA, Cubitus Anterior; J, Jugal; lf, longitudinal fold; MP, Media Posterior; RA, Radius Anterior; RP, Radius Posterior; ScA, Subcosta Anterior; tf, (Fig. A beetle's functional wings, which allow flying, are the hind wings. Beetle wings are composed of a forewing (also known as elytron) and a hind wing. presents its own set of problems2 such as formation of stress concentrators or degradation We determined the relationship between composition and mechanical properties of elytra (modified forewings that are composed primarily of highly sclerotized dorsal and less sclerotized ventral cuticles) from the beetles Tribolium castaneum (red flour beetle) and Tenebrio molitor (yellow mealworm). The nanomechanical properties of multilayer elytron cuticle of. E-mail: known metric function of the phenomenologically symmetric geometry of two sets of rank (n + 1,n), we find the metric function of the phenomenologically symmetric geometry of rank (n + 1, n + 1), on the basis of which we find later the metric function of the phenomenologically symmetric geometry of rank (n+1, n+2). 3), whose relationship with function will be discussed. isotropic elastic properties at the millimeter scale. Mimicking unfolding motion of a beetle hind wing, of a beetle’s free flight and a flapping-wing system that mimics beetle, dependent reversible mechanical interlocking using beetle-inspired, K. Y. The hydrophobic region exhibits robust water-repelling performance during the dynamic droplet impact. Poisson’s ratio in the chordwise direction is 0.63–0.73 and, approximately twice as large as that in the spanwise direction, (0.33–0.39), and it can be concluded that the membrane of a, beetle’s hind wing is an anisotropic and non-homogeneous, To investigate the cross-linking relationships between compo-, nents, the hydration and mechanical properties of the elytra of. The microstructure of the wax coating consists, of flattened hemispheres (10 mm diameter) arranged in regular, hexagonal arrays (Fig.
