Predicting the high strain rate behaviour of particulate composites using time-temperature superposition based modelling [PDF]

open access: yesEPJ Web of Conferences, 2021
Polymeric particulate composites are widely used in engineering systems where they are subjected to impact loading – at a variety of temperatures – leading to high strain rate deformation.

Rubber aging life prediction based on interpolation and improved time-temperature superposition principle

open access: yesMaterials Research Express, 2022
With focus on quickly and accurately predicting and evaluating the aging performance degradation of rubber at room temperature, the pseudo-failure life at each different acceleration temperature is proposed to be calculated by interpolation method based ...

The Effect of Natural Multidecadal Ocean Temperature Oscillations on Contiguous U.S. Regional Temperatures. [PDF]

open access: yesPLoS ONE, 2015
Atmospheric temperature time series for the nine climate regions of the contiguous U.S. are accurately reproduced by the superposition of oscillatory modes, representing the Atlantic multidecadal oscillation (AMO) and the Pacific decadal oscillation (PDO)

Temperature-Time Superposition Effect on Compressive Properties of AZ31B Magnesium Composite Foams

open access: yesMetals, 2018
Magnesium composite foams with 10 vol. % of hollow ceramic microspheres (CMs) were prepared by modified melt foaming method. Specimens with homogeneous pore structures were subjected to various heating temperature (150, 250, 320, 400, and 500 °C ...

Long-term creep behavior of self-reinforced PET composites

open access: yeseXPRESS Polymer Letters, 2017
Creep deformation of polymers results from their inherent viscoelastic nature that changes polymer’s shape with time. Creep response represents an important property of thermoplastic composites that affects their dimensional stability, especially in ...

FRACTIONAL TIME-TEMPERATURE SUPERPOSITION MODEL OF VISCOELASTIC MATERIAL WITH VERTICAL SHIFT FACTOR

open access: yesJixie qiangdu, 2021
The dynamic properties of the viscoelastic material have remarkable temperature-frequency effect. In order to characterize the dynamic properties of the viscoelastic material more precision,on the basis of the fractional constitutive model and the time ...

Star Polymers and the Failure of Time−Temperature Superposition [PDF]

open access: yesMacromolecules, 1998
We model the arm of a star polymer as an anchored random walk in an array of fixed obstacles with the added assumption of an energetic cost associated with the walk retracing its previous step. By including this energetic penalty for such "hairpin" turns on the chain, we are able to account for the thermorheological complexity of long-branched ...
