“…This is because the plastic stage can absorb more energy. From the point view of energy absorption, it can be seen that the ratio of the energy at failure over the energy of elastic is, E u /E e ≈ 1.98 (4) Which shows that the material can consume about the same energy of elastic after yield load. In addition, the ductility ratio of the membrane materials can be calculated as σ y /σ e .…”

“…The combination of yarns and coating can provide good mechanical strength and excellent chemical properties including being waterproof, thermal insulation, corrosion-resistant, etc. Numerous instances of damage and even accidents leading to destruction have emerged [ 4 , 5 ]. The failure of membrane materials generally does not result from the ultimate tensile strength obtained when the material is undamaged [ 6 , 7 ].…”

The emphasis of this study is placed on the investigation into the failure mechanisms of the fabric membranes when exposed to such defective cracks. This experimental study investigates the initial crack of a flat circle and conducts a uniaxial shear test on the membrane materials. The deformation of the membrane materials is obtained through an optical non-contact scanner. Our study has been conducted to assess the crack propagation of fabric membrane materials at different angles. The relationships between crack width and stress together with stress and strain are also obtained. Based on the results, a mechanic of failure on the membrane was proposed. Moreover, new findings into the ductility and energy absorption of the fabric membrane materials have been established to inform the failure mechanisms.

Coated fabric is a composite textile consisting of fiber‐based cloth and surface coating. It features advantages such as lightweight, high strength, and multifunctionality, making it highly popular in architectural membrane structures. However, conventional coated fabrics have been facing bottlenecks such as short service life, difficult maintenance, and low dimensional stability. This paper introduces an innovative high‐performance PVC coated polyester named Flexlight Xtrem TX30, which possesses excellent longevity and durable aesthetics. The uniaxial tensile properties of three types of TX30 polyesters in the warp, weft, and 45° directions were comprehensively revealed through monotonic and cyclic tests. First, mono‐uniaxial tensile tests were performed on six specimens for each case. The failure characteristics were observed and strength at different angles was determined. Benefiting from the precontraint technology, the difference in strength between the warp and weft directions for TX30 is less than 5%. Second, uniaxial cyclic tensile tests were conducted on four specimens for each case. The initial tensile behavior exhibited the highest nonlinearity, with an R‐squared value greater than 0.999 for the cubic stress–strain relation. By the 15th cycle, the stiffness increment for all cases is less than 1%, indicating the attainment of material stabilization. Additionally, ratcheting effect and hysteresis loops were observed during the tests. The ratcheting strain and dissipated energy across different cases were thoroughly discussed and compared. In general, the experimental investigations in this study facilitate the understanding of the mechanical characteristics of the novel TX30 polyesters, providing insights for engineering applications and academic research.Highlights The uniaxial tensile properties of innovative TX30 polyesters were investigated. The failure mechanism and tensile strength at different angles were identified. The nonlinear stress–strain relations and cyclic material behaviors were determined.
