Abstract
Proposed is a novel viscoelastic testing method for evaluating the viscoelastic behaviors of rubber nanocomposites under large prestrains. A small-amplitude sinusoidal strain is added superimposed on a static strain to obtain storage and loss moduli. Intracycle nonlinearities are analyzed for large-amplitude oscillatory extension under significantly large prestrains. The method is effective to capture the complex viscoelastic responses, which can facilitate the development of accurate nonlinear viscoelastic constitutive models.
