Stress relaxation of near-critical gels [PDF]

Physical 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.

Lipopolysaccharide, high glucose and saturated fatty acids induce endoplasmic reticulum stress in cultured primary human adipocytes : salicylate alleviates this stress [PDF]

, 2010
Recent findings indicate that endoplasmic reticulum (ER) stress is significantly increased in adipose tissue of obese human subjects and is critical to the initiation and integration of pathways of inflammation and insulin action.

Stresses Inside Critical Nuclei

The Journal of Physical Chemistry B, 2004
The usual derivation of classical nucleation theory is inappropriate for crystal nucleation. In particular, it leads to a seriously flawed estimate of the pressure inside a critical nucleus. This has consequences for the prediction of possible metastable phases during the nucleation process. In this paper, we reanalyze the theory for crystal nucleation

Critical condition parameters and kinetics of dynamic recrystallization for hot deformed 1 wt%Cr-1 wt%Mo rotor steel

Materials Research Express, 2020
Isothermal hot compression tests of low alloy 1 wt%Cr–1 wt%Mo medium carbon rotor steel were carried out over the temperature range from 850 °C–1050 °C under three strain rates $\left(\dot{\varepsilon }\right)$ varying from 0.001 s ^−1 –0.1 ^.1 s ^−1 ...

Critical applied stresses for a crack initiation from a sharp V-notch [PDF]

Fracture and Structural Integrity, 2014
The aim of the paper is to estimate a value of the critical applied stress for a crack initiation from a sharp V-notch tip. The classical approach of the linear elastic fracture mechanics (LELM) was generalized, because the stress singularity exponent ...

Voids Nucleation at Inclusions of Various Shapes in Front of the Crack in Plane Strain

Archives of Metallurgy and Materials, 2016
An analysis is presented of the stress field in and around inclusions of various shapes. Results were obtained by the finite element method. Inclusions were located within elementary cells located at the centre of the specimen next to the crack front ...
