Application of Kramers–Kronig relations to time–temperature superposition for viscoelastic materials

Dynamical mechanical analysis (DMA) is an experimental technique commonly used to study the frequency and temperature dependence of the mechanical properties of viscoelastic materials. The measured data are traditionally shifted by application of the time–temperature superposition principle to obtain the master curves of the viscoelastic material. The goal of this work is to present a methodology to determine the horizontal and vertical shift...
