“…FE software packages were developed to simplify often complicated simulation processes. They are especially very common in engineering applications [ 3 , 4 , 5 ] and are becoming increasingly popular in the investigation of the mechanical behavior of biological structures, such as complex human and animal body parts [ 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ].…”

The finite element (FE) method is one of the most widely used numerical techniques for the simulation of the mechanical behavior of engineering and biological objects. Although very efficient, the use of the FE method relies on the development of accurate models of the objects under consideration. The development of detailed FE models of often complex-shaped objects, however, can be a time-consuming and error-prone procedure in practice. Hence, many researchers aim to reach a compromise between the simplicity and accuracy of their developed models. In this study, we adapted Distmesh2D, a popular meshing tool, to develop a powerful application for the modeling of geometrically complex objects, such as insect wings. The use of the burning algorithm (BA) in digital image processing (DIP) enabled our method to automatically detect an arbitrary domain and its subdomains in a given image. This algorithm, in combination with the mesh generator Distmesh2D, was used to develop detailed FE models of both planar and out-of-plane (i.e., three-dimensionally corrugated) domains containing discontinuities and consisting of numerous subdomains. To easily implement the method, we developed an application using the Matlab App Designer. This application, called WingMesh, was particularly designed and applied for rapid numerical modeling of complicated insect wings but is also applicable for modeling purposes in the earth, engineering, mathematical, and physical sciences.

“…These literature data aimed to elucidate the working principles that the insects applied in their evolution to keep a firm foreand hindwing coupling and overcome millions of wingflapping cycles in flight without damage. 15,16 Since 2019, Prof. Gorb and his collaborators have consistently studied the wing-coupling mechanisms of insects, especially the hook-furrow coupling of honeybees [5][6][7]17 (this study). In detail, the bee wing-coupling is generally composed of a set of hamuli (hooks) at the leading edge of the hindwing and a posterior recurved margin (PRM) at the trailing edge of the forewing (Fig.…”

“…In recent years, studies on the biomechanics and functionality of the fore-and hindwing coupling have been mainly focused on three types of wing-coupling mechanisms, including hook-furrow coupling (caddisflies, bark lice, and bees), [1][2][3][4][5][6][7] clamp-furrow coupling (bugs) [8][9][10][11][12][13] and amplexiform coupling (butterflies). 14 The above literature demonstrated the comparative morphology and biomechanical properties (including sliding-friction reduction and anti-structural-damage strategies) of wing-couplings among two or more insect groups.…”

“…1). Until now, the structure, material composition, biomechanics, aerodynamics and even bioinspired application of the bee wing-coupling, to some extent, have been systematically investigated, [5][6][7]17 devoted to revealing the likely significance of cuticle sclerotization and hamulus morphology on the performance of the coupling. However, one issue which needed to be improved on the mechanical properties of the coupling was only focusing on the mechanical performance of hamuli without considering the PRM deformation as well as the likelihood of its structural failure.…”

“…For this purpose, we estimated the elastic modulus of 600 uniformly distributed points on the rostrum and then measured their mean value. The Poisson's ratio of the model was set as 0.3, which is the same as that of many previously investigated biological materials [20] and has frequently been used for models of insect cuticle [21][22][23].…”

Elongated rostra (snouts) are remarkable features of many female weevils. The female of Curculio glandium uses the snout to excavate channels in acorns to oviposit. Considering the slenderness of the rostrum, the excavation of channels in solid substrates without buckling is a challenging task from both engineering and biological points of view. Here we aimed to examine the roles of the material properties and morphology of the rostrum in its buckling resistance. We employed microscopy techniques, non-destructive material characterisation and finite element (FE) modelling to shed more light on the excavation mechanics of the rostrum. We found that sexual dimorphisms are present not only in the length but also in the material, particularly the elastic modulus, and morphological features, particularly the curvature and thickness of the cuticular layers. Our FE modelling showed that those factors play essential roles to maximise the buckling resistance and minimise the bending resistance of the female rostrum. Considering that during excavation, the rostrum needs to be straightened without buckling, the functionality of the rostrum is likely to be a compromise between the flexibility and stiffness.
