The paper describes that after the imposition of a large strain probe in non-aging conditions, the BKZ nonlinear viscoelastic constitutive equation can qualitatively predict a decrease in a followed by its rapid increase. A modified form of BKZ constitutive equation with an aging clock is used to describe the evolution of the viscoelastic response in type II history. The predictions from this model describe the experimental results from this laboratory. This quantitative demonstration of the importance of accounting for material memory effects when interpreting the viscoelastic response of polymeric glasses.
