Viscoelastic behavior and construction of master curve for graphene/polyimide nanocomposites
High Performance Polymers, 2016Dynamic mechanical spectroscopy is used to investigate the variation of the glass rubbery transition temperature ( T g ) of graphene/polyimide nanocomposites. The T g was obtained as the temperature corresponding to the peak of the tan δ versus ...

Quantification of Uncertainty in the Master Curves of Viscoelastic Properties of Asphalt Concrete
Advances in Civil Engineering Materials, 2018Abstract The prediction of asphalt concrete (AC) behavior using a continuum damage mechanics approach requires viscoelastic properties like creep compliance (CC) and relaxation modulus (RM) values. Because of practical limitations, dynamic modulus (DM) and phase angle (PA) measurements are used to construct CC and RM master curves ...

Dynamic Backcalculation of Viscoelastic Asphalt Properties and Master Curve Construction
Transportation Research Record: Journal of the Transportation Research Board, 2017In this study, dynamic backcalculation was conducted on two selected Long-Term Pavement Performance (LTPP) sections, one from a cold climate zone and the other from a warmer climate zone. It was demonstrated that not only the viscoelastic dynamic modulus (| E*|) of the asphalt has been backcalculated from an extensive set of field data but also the ...

Rheologica Acta, 2012
We use fractional viscoelastic models that result from the application of fractional calculus to the linear viscoelastic theory to characterize thermorheologically simple linear viscoelastic materials. Model parameters are obtained through an optimization procedure that simultaneously determines the time–temperature shift factors. We present analytical

Evaluation of viscoelastic master curves of filled elastomers and applications to fracture mechanics
Journal of Physics: Condensed Matter, 2008The viscoelastic response of filler-reinforced elastomers has been investigated by dielectric- and dynamic-mechanical spectroscopy. Horizontal and vertical shifting factors are evaluated, which are used for the construction of viscoelastic master curves.

Master Creep Compliance Curve for Random Viscoelastic Material Properties
2013The objective of this study is to apply the time-temperature superposition principle (TTSP) to the viscoelastic material functions that exhibit a large degree of variability to predict the long-term behavior of a vinyl ester polymer (Derakane 441–400). Short-term tensile creep experiments were conducted at three temperatures below the glass transition ...

Journal of Sound and Vibration, 1985
Fibre and wire reinforced flexible viscoelastic pipes are used in situations where their static and dynamic characteristics provide much better performance than metallic pipes. Because of their vibration and shock attenuation characteristics, these viscoelastic pipes are used as flexible conduits in applications where it is desirable to minimize the ...

Strain, 2018
AbstractA simple procedure for measuring two independent material properties of a viscoelastic material is proposed. Poisson's ratio is directly measured using digital image correlation during dynamic viscoelasticity test. Therefore, the complex Poisson's ratio as well as the complex modulus is simultaneously obtained from same specimen under same ...

Linear viscoelastic master curves of neat and laponite-filled poly(ethylene oxide)–water solutions
Rheologica Acta, 2006Aqueous solutions composed of dispersed nanoparticles and entangled polymers are shown to exhibit common viscoelasticity over a range of particle and polymer concentrations. Time–temperature superposition and time–concentration superposition are applied to generate rheological master curves for neat and laponite-filled aqueous solutions of poly ...
