“…When the PVC coated fabric is in tension, a phenomenon referred to as crimp interchange occurs. It is one of the most important factors leading to the severe nonlinearities in the mechanical behavior of the coated fabric [6,7,14,15]. As mentioned in Section 1, there is an interconnection between the behavior of the membrane's material and its configuration.…”

“…Thus, the material model used for the PVC coated fabric should be computationally inexpensive. In [6], the present authors have proposed an elasto-plastic model for coated fabrics which has proven to capture their salient mechanical behavior. The material model has been developed in the small deformation framework, but it can also be applied to large deformation problems in ABAQUS because before the user material subroutine (UMAT) is called, the strain and stress tensors have been rotated to take into account for rigid body motion in every increment.…”

“…Therefore, to gain a better assessment of the feasibility of the design concept, a single tension membrane unit is analyzed first. Moreover, through this analysis the material constitutive model, which we have developed for coated fabrics in [6], is further validated for a different load case. Because of these reasons, the success of this analysis will thus be the premise for further investigation of the feasibility of this design concept.…”

“…Moreover, the mechanical behavior of coated fabrics used for membrane structures is also very complicated. It includes anisotropy, plasticity, time dependency and load ratios dependency [6][7][8][9]. More than fifty years after the pioneering work of Otto et al [10], the development of tension structures has been hampered because of limitations in analysis methodologies [11].…”

Mit DIN EN 17117‐1 liegt seit etwa einem Jahr erstmals eine europäische Norm zur Durchführung und Auswertung von biaxialen Zugversuchen an beschichteten Textilien vor, wie sie im Membranbau Anwendung finden. Der vorliegende Beitrag bietet eine Vorstellung, Analyse und Bewertung der neuen Regelungen. Besondere Neuerungen gegenüber der bisherigen Versuchspraxis wie Regelungen zur Probekörpergeometrie, zum Lastprotokoll und der Belastungsgeschwindigkeit werden erläutert und bewertet. Der Beitrag zeigt den Unterschied zwischen elastischen Bemessungs‐ und Vergleichskonstanten und zeigt beispielhaft deren Anwendung und Interpretation.

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.
