| Abstract: | The applicability of a strain-coupling integral constitutive equation to the analysis of the nonlinear viscoelasticity of branched polymers is evaluated. A simpler and more efficient method is proposed for evaluating the material functions of the strain-coupling constitutive equation. |
| Keywords: | Strain coupling double-step experiment nonlinear viscoelasticity |
