Implementation of an Elasto-Viscoplastic Model of Geosynthetics in ABAQUS
Polymer geosynthetics exhibit obvious viscous behaviors related to the loading strain rate. A nonlinear three-component elasto-viscoplastic constitutive model is found relevant to simulate these rate-dependent load-strain behaviors of polymer geosynthetics under complex loading conditions, including variable loading rate, creep and stress relaxation. For the purpose of the wide use of this model, it is implemented into the finite element analysis software ABAQUS through its user material subroutine (UMAT) connector. The algorithm used for the numerical integration of the constitutive model is return mapping method and is presented in detail in this paper. Then FEM simulations are performed to validate that this model is very capable of simulating the viscous behaviors of geosynthetics under arbitrary loading conditions.
