A recently developed strain‐coupling constitutive equation for nonlinear viscoelasticity is used to analyze extensional flows. Comparisons are presented between the predictions of the theory and experiment for equibiaxial‐ and uniaxial‐step strain‐stress relaxation experiments. © 1993 John Wiley & Sons, Inc.
