A non-linear viscoelastic model is introduced by employing a new formulation where the relaxation time of rate processes is directly dependent on the induced deformation state applied to the material. The plastic flow of amorphous polymers is considered as a continuous structural change, and the yie
## Abstract **Summary:** Using molecular dynamics simulations, we determine the linear and nonlinear viscoelastic properties of a model polymer melt in the unentangled regime. Several approaches are compared for the computation of linear moduli and viscosity, including GreenβKubo and nonequilibrium
