On the Williams—Watts function of dielectric relaxation [PDF]
Proceedings of the National Academy of Sciences, 1984 It has been observed over the past 15 years that experimental frequency-dependent dielectric constants of broad classes of materials including polymeric systems and glasses may be interpreted in terms of the Williams-Watts polarization decay function [Formula: see text] The exponent α and the time constant T depend ...

Mathematical and Computational Applications, 2023 In this paper, we study the long-time behavior of a weakly dissipative viscoelastic equation with variable exponent nonlinearity of the form utt+Δ2u−∫0tg(t−s)Δu(s)ds+a|ut|n(·)−2ut−Δut=0, where n(.) is a continuous function satisfying some assumptions and

Recent Advances in the Calculation of Dynamical Correlation Functions
Frontiers in Physics, 2020 We review various theoretical methods that have been used in recent years to calculate dynamical correlation functions of many-body systems. Time-dependent correlation functions and their associated frequency spectral densities are the quantities of ...

Memory function for dielectric relaxation
The Journal of Chemical Physics, 2000 The second-order memory function (SOMF) for the dicyclohexylmetyl-2metyl succinate is obtained by using simple numerical manipulation of the experimental dielectric data. According to the prescription given in a previous paper [J. Chem. Phys. 109, 9057 (1998)], the frequency behavior of the real and imaginary parts of the SOMF is discussed in terms of ...

Relaxation function of 3D XY model [PDF]
Physica B+C, 1977 Abstract The Method of Mori has been extended in an effort to study the relaxation function. The difficulty posed by continued fractions has been in some special cases overcome to obtain exact solutions for the relaxation function. The physical significance of our solution is discussed with aid of the XY model.

Creep and relaxation responses of fly ash concrete: Linear and nonlinear cases
Case Studies in Construction Materials, 2022 The application of reinforced concrete has been used in various engineering and architecture fields. Stress relaxation and creep are two crucial time-dependent behaviours of concrete. The influence of two behaviours is closely related to the service life

Effect of thermal modification on the stress relaxation behavior and microstructure of the cell wall
Journal of Wood Science, 2023 The stress relaxation behavior and cell wall microstructure of sugi were evaluated after thermal modification. Stress relaxation is observed and has a broad relaxation spectrum, implying various relaxation mechanisms.

Revisiting the modeling of quasielastic neutron scattering from bulk water [PDF]
EPJ Web of Conferences, 2022 Quasi-elastic neutron scattering (QENS) from bulk-water at 300 K, measured on the IRIS backscattering neutron spectrometer (ISIS, UK), is interpreted using the jump diffusion model (JDM), a “minimalistic” multi-timescale relaxation model (MRM) and ...
