The publications on DMA are full of complex ideas and daunting math that do not typically attract the interest of designers and engineers tasked with developing products, even though the underpinnings of viscoelastic theory govern everything that happens to our plastic products once they are in use.
In this paper, the soil element is regarded as a viscoelastic element with fractional-derivative properties and the exact expression of the displacement and stress of the infinite fractional-derivative viscoelastic soil surrounding the biogas digester is deduced based on the viscoelastic theory. In our research, the thickness of the mold structure also can be considered.
In this paper, firstly the mechanism of complicated volume strain in brittle rock is analyzed by the viscoelastic theory. Then, we present a fractional viscoelastic volume strain model and the volume strain formulas are derived under a constant-strain-rate loading, respectively.

Thus, more internal energy dissipation would occur by long-eared owl flight feather due to its molecular friction during the deformation process on the basis of viscoelastic theory.
Obviously, the relationships of log G' ~ log [omega] and log G" ~ log [omega] depart from the quantitative description of log G' [infinity] 2 log [omega] and log G" [infinity] log [omega] given by linear viscoelastic theory (26).
The authors present a unified mechanics and materials perspective on polymers: both the mathematics of viscoelastic theory and the physical mechanisms behind polymer deformation processes.

In the linear viscoelastic theory, creep and stress-relaxation curves are proportional.
[15] studied HDPE (high density polyethylene) in the small strains domain in order to develop a model based on tensile relaxation data using Schapery's viscoelastic theory: they mainly attributed the larger discrepancies between experimental data and modeling results to the viscoplastic effects that were not included in the model.
This award perpetuates the memory of Melvin Mooney, the developer of viscoelastic theory, the Mooney viscometer and other testing equipment, by honoring Rubber Division members and affiliate members who have exhibited exceptional technical competence by making significant and repeated contributions to rubber technology.
Based on viscoelastic theory, a standard uniaxial linear viscoelastic solid model for creep under constant stress [[sigma].sub.o] (MPa) is:
