Abstract
The rate-dependent behaviors of polymer geosynthetics have been observed in the special tensile tests under various loading histories, including the step-changed strain rate loading, creep and stress relaxation applied during otherwise monotonic loading. All the investigated polymer geosynthetics show significant loading rate effects, creep deformation and stress relaxation. An elasto-viscoplastic constitutive model described in a non-linear three-component model framework is developed to simulate the rate-dependent behaviors of polymer geosynthetics. The developed constitutive model is verified by comparing its simulated results with the experimental data of polymer geosynthetics presented in this study and those available from the literature. ฉ 2010 Elsevier B.V.
