A strain-coupling integral constitutive equation for non-linear viscoelasticity is evaluated using double-step shear strain experiments. Evaluation of the functions of the theory is discussed, and it is shown that the theory provides satisfactory descriptions of strain and time variations for doublestep stress relaxation experiments.
