“…This failure of Larson model at high shear rates could be attributed to the probability that the polymer strands could not contact to the extent, equivalent to what is described by the single strain‐softening parameter( ξ') in the Larson model, because the shear rates are too fast. It is like the situation that the damping function predicted by the Doi–Edwards theory are stronger than the experimental data, because the retraction of the polymer strands is complete inside the virtual tube proposed by Doi and Edwards . The experimental and the predicted η E data are illustrated in Figs.…”

“…The damping function, h ( γ ), has been a concept introduced in rheology since more than 30 years ago, and its implementation in the modeling of polymer melts was an essential step forward in the classification and understanding of nonlinear viscoelasticity . Most of nonlinear viscoelastic behaviors can be described by utilizing h ( γ ) determined from stress relaxation measurements .…”
