Stress relaxation of near-critical gels [PDF]

open access: yesPhysical Review E, 2001
The time-dependent stress relaxation for a Rouse model of a crosslinked polymer melt is completely determined by the spectrum of eigenvalues of the connectivity matrix. The latter has been computed analytically for a mean-field distribution of crosslinks.

Overdamped stress relaxation in buckled rods [PDF]

open access: yesPhysical Review E, 2004
We present a comprehensive theoretical analysis of the stress relaxation in a multiply but weakly buckled incompressible rod in a viscous solvent. In the bulk two interesting regimes of generic self--similar intermediate asymptotics are distinguished, which give rise to two classes of approximate and exact power--law solutions, respectively.

Influence of supramolecular forces on the linear viscoelasticity of gluten [PDF]

open access: yes, 2016
Stress relaxation behavior of hydrated gluten networks was investigated by means of rheometry combined with μ-computed tomography (μ-CT) imaging. Stress relaxation behavior was followed over a wide temperature range (0–70 °C).

Anisotropic Local Stress and Particle Hopping in a Deeply Supercooled Liquid [PDF]

open access: yes, 2002
The origin of the microscopic motions that lead to stress relaxation in deeply supercooled liquid remains unclear. We show that in such a liquid the stress relaxation is locally anisotropic which can serve as the driving force for the hopping of the ...

Calculation of Relaxation Spectra from Stress Relaxation Measurements [PDF]

open access: yes, 2010
Application of stress on materials increases the energy of the system. After removal of stress, macromolecules comprising the material shift towards equilibrium to minimize the total energy of the system.

Stress relaxation analysis of single chondrocytes using porohyperelastic model based on AFM experiments

open access: yesTheoretical and Applied Mechanics Letters, 2014
Based on atomic force microscopytechnique, we found that the chondrocytes exhibits stress relaxation behavior. We explored the mechanism of this stress relaxation behavior and concluded that the intracellular fluid exuding out from the cells during ...

Examining Stress Relaxation in a Dissimilar Metal Weld Subjected to Postweld Heat Treatment [PDF]

open access: yes, 2018
Dissimilar metal welds are often required in nuclear power plants to join components made from austenitic steels to those from ferritic steels, particularly in fast breeder reactor plants, in order to join the intermediate heat exchanger to the steam ...

Effect of stress relaxation on accelerated physical aging of hydrogenated nitrile butadiene rubber using time-temperature-strain superposition principle

open access: yesAdvanced Industrial and Engineering Polymer Research, 2019
While the stress relaxation is a common phenomenon for polymers, its effect on the stress/strain accelerated aging of the hydrogenated nitrile butadiene rubber (HNBR) cannot be ignored.
