Uniaxial cyclic tensile mechanical properties of ethylene tetrafluoroethylene (ETFE) foils.

Highlights: [•] Uniaxial cyclic tensile mechanical properties are investigated under eight loading cases. [•] Elastic modulus divided into three parts explains deformation discrepancy of ETFE foil structure. [•] Yield point is determined by the elastic modulus of 70MPa to minimize strain difference. [•] Ratcheting strain and hysteresis loop area at the 16th cycle are found to be approximate stable. [•] Obtained values are useful for analyzing structural stress, deformation and energy dissipation. [Copyright &y& Elsevier]
