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

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 ...

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.

Stretched-exponential decay functions from a self-consistent model of dielectric relaxation [PDF]

, 2007
There are many materials whose dielectric properties are described by a stretched exponential, the so-called Kohlrausch-Williams-Watts (KWW) relaxation function.

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 ...

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 ...
