A five-parameter fractional derivative model and a hereditary model are being studied to predict polyurethane foam's uniaxial responses under harmonic excitation. A system identification procedure is developed to estimate the model parameters. The prediction results from both models are presented and compared. Both models provide reasonably good prediction of the observed responses from different input levels at a given compression level.
