The Pad&-Laplace method using the Laplace transform and the Pad& approximants has been used to recover a discrete relaxation spectrum from dynamic oscillatory data in the molten state for polymers. The method detects by its own stability the number of modes of the spectrum and has been shown to be a
Accurate and reliable determination of the linear viscoelastic relaxation spectrum is a critical step in the application of any constitutive equation. The experimental data used to determine the relaxation spectrum always include noise and are over a limited time or frequency range, both of which ca
