Stress Relaxation in Entangled Polymer Melts [PDF]
, 2010 We present an extensive set of simulation results for the stress relaxation in equilibrium and step-strained bead-spring polymer melts. The data allow us to explore the chain dynamics and the shear relaxation modulus, $G(t)$, into the plateau regime for ...

Stress relaxation models with polyconvex entropy in Lagrangean and Eulerian coordinates [PDF]
, 2013 The embedding of the equations of polyconvex elastodynamics to an augmented symmetric hyperbolic system provides in conjunction with the relative entropy method a robust stability framework for approximate solutions \cite{LT06}.

Modeling and Verification of Stress Relaxation Behavior of Ti-6Al-4V [PDF]
MATEC Web of Conferences, 2020 The phenomenon of gradual decrease of internal stress with the deformation of material maintained under the precondition of certain temperature and initial stress or pre-strain is called stress relaxation.

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

Simulation of relaxation time and storage modulus for carbon nanotubes-based nanocomposites
Journal of Materials Research and Technology, 2021 This paper develops two equations for relaxation time and storage modulus of biopolymer nanocomposites at unlike frequency ranges. The relaxation time is correlated to zero complex viscosity, yield stress, K constant and power-law index. In addition, the

Shear flow effects on phase separation of entangled polymer blends [PDF]
, 1998 We introduce an entanglement model mixing rule for stress relaxation in a polymer blend to a modified Cahn-Hilliard equation of motion for concentration fluctuations in the presence of shear flow.

After stress comes relax(ation)
New Journal of Physics, 2015 Viscoelastic materials take a finite time to relax and dissipate stress and this time scale is directly connected to the microstructure of the material itself. In their paper, Gomez-Solano and Bechinger (2015 New J. Phys.
