“…The constitutive relations are built based on the microstructures of yarns, coatings and the frictions between them [51,52]. As shown in Figure 4, there are many existing microscopic models mainly used in the textile industry to help improve the material performances, including Peirce model [53], Freeston model [54], Testa model [55], hinged truss model [56], space truss model [57], trapezoid truss model [58], grid model [59], Pargana model [60,61], etc. The prediction accuracy is high, but complex expressions limit its applications in the analysis of civil engineering.…”

Membrane structures are widely used in large span spatial structures due to excellent mechanical behavior and beautiful forms. Mechanical properties of coated fabrics are an important basis of design, analysis, and construction of membrane structures. This paper gives an overview of the research advances in mechanical properties of coated fabrics. First, the basic mechanical indexes of coated fabrics and corresponding test methods are presented. Then, the existing constitutive relations for coated fabrics are discussed. Finally, the effect of environment and other factors on the mechanical properties of coated fabrics are studied. In addition, the future trends on the mechanical behavior of coated fabrics are given, which can be references for design and analysis of coated fabrics in civil engineering.

“…The physical interpretation of model parameters is clear, and the description of the constitutive relation is more accurate. Researchers have established constitutive relations based on the microstructures of yarns, coatings and their interactions [17][18][19] through the combination of mechanical concepts and mathematical analysis, and have proposed Tensioned Fabric Structures, 20 hyperelastic constitutive model, 21 micro-mesa unit cell model, 22 yarn model, 23 digital element methods [24][25][26] and multi-layer solid elements method, 19 etc. Among the studies, Gade et al 17 established a meso-scale model with regard to the coating stiffness, by performing an inverse process of parameter identification using Levenberg-Marquardt algorithm, and the model is implemented as a material law into a finite element program.…”

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.

“…Their behaviour model is non-linear and anisotropic and takes into account the hysteresis observed during biaxial tests composed of a loading and followed by an unloading. Furthermore, Pargana et al (2007) and Pargana and Leitao (2015) proposed a similar model that they could implement in a membrane finite element in order to simulate tensioned fabric structures. King et al (2005) also propose another similar model based on the yarns and the weaving properties for a Kevlar-fibre woven fabric that they implemented in Abaqus.…”

This paper deals with the modelling of the mechanical behaviour of coated woven fabric. The proposed model takes into account the individual behaviours of the yarns, the coating and their interactions including the influence of the angle variation between warp and weft yarns. This model is able to describe simultaneously the non-Newtonian viscous behaviour, the timeindependent irreversibility, the anisotropy and the cyclic loading behaviour. The model was implemented in the finite element code ABAQUS and enables calculations on structures such as complete sails.
