Time-Temperature Superposition

2016
This chapter consists of three sections: the fundamentals, the geometric interpretation, and the algorithms of time-temperature superposition. The first section deals with the phenomenology, mathematical formulas, models for horizontal shift factor, and molecular explanation of time-temperature superposition.

Time-Temperature Superposition Based Accelerated Aging Method for Packaged MEMS Resonators

2022 Joint Conference of the European Frequency and Time Forum and IEEE International Frequency Control Symposium (EFTF/IFCS), 2022
SummaryThis manuscript introduces a new methodology to accelerate and predict stress-related aging in encapsulated MEMS resonators. This approach builds upon the time-temperature superposition principle that, in linear viscoelastic materials, relates the

Time-Temperature Superposition of the Dissolution of Silk Fibers in the Ionic Liquid 1-Ethyl-3-methylimidazolium Acetate.

Biomacromolecules, 2021
This study investigated the dissolution of silk multifilament fibers in the ionic liquid 1-ethyl-3-methylimidazolium acetate. The dissolution process was found to create a silk composite fiber, comprising undissolved silk multifilaments surrounded by a ...

Predicting Solute Diffusivity in Polymers Using Time–Temperature Superposition

The Journal of Physical Chemistry B, 2022
We demonstrate a novel application of the time-temperature superposition (TTS) principle to predict solute diffusivity D in glassy polymers using atomistic molecular dynamics simulations. Our TTS approach incorporates the Debye-Waller factor ⟨u2⟩, a measure of solute caging, along with concepts from thermodynamic scaling methods, allowing us to balance

Long-term creep behaviour of E-glass/epoxy composite: Time-temperature superposition principle

Plastics, Rubber and Composites: Macromolecular Engineering, 2020
Creep behaviour of an epoxy matrix composite with a similar arrangement of composites used in a root joint of a wind turbine blade is investigated in this research. The vacuum infusion process was used to manufacture the composite.

Time‐temperature superposition in two‐phase polyblends

Polymer Engineering & Science, 1974
AbstractThe temperature dependence of the mechanical properties of a 50/50 blend of PVAC and lightly crosslinked PMMA has been examined using the data of Kawai et al. The shift distances, log aT, were generated by bringing the experimental data into coincidence on master curves calculated from a Takayanagi model whose parameters were varied in ...
