Time–Temperature–Plasticization Superposition Principle: Predicting Creep of a Plasticized Epoxy [PDF]
Polymers, 2019 Long-term creep properties and the effect of water are important for fiber reinforced polymer (FRP) composite materials used in offshore applications. Epoxies are often used as a matrix material in such composites. A typical design lifetime of offshore FRP structures is 25 or more years in direct contact with water leading to some deterioration of the ...

A comparison of two algorithms for applying the time-temperature superposition principle [PDF]
The Journal of the Acoustical Society of America, 1990 The time-temperature superposition principle provides a method of extending the effective frequency range of dynamic modulus and loss factor data of viscoelastic materials. The principle states that data collected over a limited frequency range at one temperature can be superposed over data collected at some other temperature in order to extend the ...

Applicability condition of time–temperature superposition principle (TTSP) to a multi-phase system [PDF]
Mechanics of Time-Dependent Materials, 2012 The applicability condition of the time–temperature superposition principle (TTSP) to a multi-phase system is analytically discussed assuming a mixture law. It was concluded that the TTSP does not hold for a multi-phase system in general but does hold for a multi-component system in which some components have the same temperature dependence and the ...

An extension of the time–temperature superposition principle to non-linear viscoelastic solids
International Journal of Solids and Structures, 2005 AbstractAn experimental data treatment is introduced to manage with the tensile test responses of highly non-linear viscoelastic solids such as solid propellants. This treatment allows the representation of a set of strain–stress curves by a single intrinsic non-linear response which is found independent of the experimental conditions of rate and ...

Applicability of the time–temperature superposition principle in modeling dynamic response of a polyurea [PDF]
Mechanics of Time-Dependent Materials, 2007 This paper addresses the applicability of the Time–Temperature Superposition Principle in the dynamic response of a polyurea polymer at high strain rates and different temperatures. Careful and extensive measurements in the time domain of the relaxation behavior and subsequent deduction of a master-relaxation curve establish the mechanical behavior for

RELAXATION PHENOMENA AND THE TIME-TEMPERATURE SUPERPOSITION PRINCIPLE
Le Journal de Physique Colloques, 1987 The time-temperature superposition principle, frequently used to describe relaxation phenomena in solids is discussed within the framework of general functions leading to sclaing with translation parallel to the horizontal axis. Finally, the concepts developed are applied to particular functions used in the literature to describe relaxation phenomena ...
