• Description:
  Several simplified one-dimensional constitutive equations for viscoelastic materials are reviewed and found to be inadequate for representing the impact-response performance of strongly nonlinear materials. Two multi-parameter empirical models are developed in accordance with consistency criteria which assure the existence of a constitutive equation. Curve-fitting procedures are derived for each model, and the models are applied to test data previously developed for Uniroyal Ensolite AAC foam rubber. The accuracy of dynamic performance representation provided by each model is assessed.
