The generalized Maxwell relaxation model of woven architectural membrane material

The uniaxial tensioned relaxation tests of woven architectural membrane material are conducted along the warp and weft direction in five different stress conditions in this paper, and the generalized Maxwell relaxation models are provided. The experimental data obtained utilizes relaxation models with three, five and seven parameters and the results demonstrate that as the number of parameters grows, the prediction precision gradually increases. When there are seven parameters, the coefficients of determination are over 99.9% at different stress levels. Therefore the generalized Maxwell relaxation model with seven parameters can effectively predict the relaxation behavior of woven architectural membranes.
