| The rheological behavior of viscoelastic materials varies with both time and temperature. Repeating DMA tests with the same material at different temperatures shifts the tan d peaks in the transition region to shorter times (higher frequencies) with increasing temperature.This is evident from figure 1, showing stress relaxation measurements made on a polymer at a series of temperatures over a time span of a minute to a week. Large differences are seen, yet only a small range of the viscoelastic response manifests itself within these time (frequency) spans. A broader picture of the time-related response is needed to understand this behavior fully. |
