“…When θ A ≠0 and θ A ≠θ T , due to the influence of coating stabilization and friction between FBs, the tension is transferred in the coated fabrics in a tension-shear coupling manner (Figure 2, sections A-S, E-S). ε y is determined by b e and b a , and its mathematical expression is as formula (6).…”

“…4 According to different modeling methods, the constitutive models of coated fabrics can be divided into two categories: continuum models and meso-structural models. 5,6 Continuum models are based on three assumptions: homogeneous, anisotropic and continuum. The stress-strain curves or response surfaces are obtained through a large amount of experiments, then mathematical expressions are established by using increments, polynomials, 7,8 etc., and finally the methods such as multi-linear and response surfaces are used to establish the constitutive model to describe the macroscopic characteristics of materials, such as geometric nonlinearity, [9][10][11] large deformation, 12 stress relaxation, 13 creep characteristics, 14 viscoelastic deformation, 15 plastic deformation, 16 etc.…”

The complex mechanical properties of coated fabrics make it difficult to obtain accurate constants for design and analysis. A high efficient constitutive model of coated plain-weave fabrics is proposed to realize the prediction of mechanical behaviours in arbitrary directions. The coupling mechanism between macro and meso deformation of coated fabrics is analyzed firstly, and the constitutive relation of the model is established based on mesoscopic parameters with clear physical interpretation. Then, the material property values of specimens are obtained by using a multi-objective optimization algorithm according to the experimental data. Unlike the previous constitutive relations which need to use finite element methods to get numerical solutions, the constitutive relation established in this paper can be mapped to a quartic equation with analytical solution, and the calculation efficiency can be greatly improved. The deviations of model predictions with experimental results, e. g., 0.052 (tension), 0.009 (width), 0.014 (length, warp), 0.025 (length, weft), 0.027 (angle, warp), 0.030 (angle, weft), show that the model predictions are in good agreement with the experimental data.

“…The increasing availability of light-weight and high-strength structural materials, in combination with advanced manufacturing techniques, has led to the conception of ever more enterprising and slender structures in modern aerospace, mechanical, and civil engineering applications [1][2][3]. As a matter of fact, the design of such advanced structures cannot be undertaken without resorting to numerical methods for structural analysis [4].…”

Nonlinear finite element analysis requires the derivation of the secant elastic stiffness matrix of the discretised mechanical system. Most approaches of the literature lead to express the secant stiffness matrix as an asymmetric matrix, which then can be made symmetric by complicated numerical calculations or analytical formulae. The paper illustrates a straightforward method for the derivation of symmetric secant (and tangent) stiffness matrices for isoparametric finite elements made of hyper-elastic materials with both geometric and material nonlinearities. The method is based on the adoption of the nodal coordinates in the current configuration, instead of the nodal displacements, as the main unknowns. The method is illustrated in general for isoparametric elements with translational degrees of freedom. Specialised expressions and numerical examples are presented for truss bar elements and structures.

“…Such free‐standing shell structures shall comprise one material only and shall stem their properties from their geometry in addition to their material. As analogy, shell structures found in nature, [ 27 ] and in various engineering structures, [ 28,29 ] have advantages in their intrinsic stability over bulk material. Via geometric design, they can access a wider range of elastic properties, way beyond their bulk material properties.…”

Nanoscale free‐standing membranes are used for a variety of sensors and other micro/nano‐electro‐mechanical systems devices. To tune performance, it is indispensable to understand the limits of aspect ratios achievable. Herein, vapor hydrofluoric (VHF) processes are employed to release 3D shell structures made of atomic‐layer‐deposited Al2O3 etch‐stop layers. Structure heights of 100–600 nm and widths of 1–200 nm are fabricated for membranes with 20 and 50 nm thickness. Undercut depths of and aspect ratios of 475:1 etch depth to structure width (50 nm films) and etch depth to membrane thicknesses of 495:0.02 (20 nm films) are achieved. The etch‐rate stagnates above a ratio of 31% hydrofluoric (HF), where decreasing EtOH shares reduce reproducibility. Etch rates reach 0.75 mm min−1 and are generally constant over vapor etch depth. For 100 nm heights and widths of , etch rates however stagnate for deeper depths. All explored structures remained stable with widths up to 5 μm independent of the height. Above width, top membranes deflect, likely from stress accumulated during deposition. Herein, exploring and understanding the limits of aspect ratio in future free‐standing membrane devices are helped.
