Abstract:
In order to further investigate the creep properties of membrane, the uniaxial creep tests were carried out based on polyvinyl chloride (PVC) coated membrane at room temperatures. The Burgers model, the modified Burgers model and the Findley power law model were adopted to simulate the experimental creep results, and precision comparisons were made. The results indicate that the creep process of the PVC coated membrane exhibit nonlinear characteristics, and the nonlinear degree is related to creep time and creep stress. The comparison of simulated and experimental creep curves shows that the fitting accuracy of creep models employed is acceptable, and all creep models can be used to describe the creep performance of the PVC coated membranes. The comparison of predicted and experimental creep curves shows that the fractional Burgers model exhibit higher accuracy, the Findley power law model for the second, the exponential Burgers model for the Burgers model for the last.
Key words: polyvinyl chloride coated membrane, woven fabric, creep property, viscoelastic model, Burger model
