Time-temperature superposition in viscoelasticity and viscoplasticity for thermoplastics

Polymer Testing, 2021
The use of thermoplastics in the automotive industry is continuously increasing. Design of parts require the characterization and numerical modelling of thermo-mechanical behaviour of those materials under wide strain rate (0–300 s−1) and temperature ...

Time: Temperature superposition principle: Application of WLF equation in polymer analysis and composites [PDF]

Zaštita Materijala, 2014
Polymers are the most studied viscoelastic material. The shorter times (high frequencies) corresponding to lower temperatures and long times (low frequencies) to high temperatures. This represents the quantitatively applied time-temperature superposition

Effect of stress relaxation on accelerated physical aging of hydrogenated nitrile butadiene rubber using time-temperature-strain superposition principle

Advanced Industrial and Engineering Polymer Research, 2019
While the stress relaxation is a common phenomenon for polymers, its effect on the stress/strain accelerated aging of the hydrogenated nitrile butadiene rubber (HNBR) cannot be ignored.
