Two-state shear diagrams for complex fluids in shear flow [PDF]

open access: yes, 1999
The possible "phase diagrams'' for shear-induced phase transitions between two phases are collected. We consider shear-thickening and shear-thinning fluids, under conditions of both common strain rate and common stress in the two phases, and present the ...

Flow stress and hot deformation activation energy of 6082 aluminium alloy influenced by initial structural state [PDF]

open access: yes, 2019
Stress-strain curves of the EN AW 6082 aluminium alloy with 1.2 Si-0.51 Mg-0.75 Mn (wt.%) were determined by the uniaxial compression tests at temperatures of 450-550 degrees C with a strain rate of 0.5-10 s(-1).

Stress-strain curve in polyethlene.

open access: yesJournal of the Society of Materials Science, Japan, 1988
The linear theory of viscoelasticity has been well formulated and successfully used in the past. In comparison, however, nonlinear viscoelastic plastic behavior at finite strains is less understood because of several complexities characteristic of polymer solids.

New nonlinear stress-strain model for loess and its comparative research

open access: yesYantu gongcheng xuebao, 2017
At present, the stress-strain curve of loess can only be described by using different mathematical models according to its morphological type. To achieve a unified description of the stress-strain mathematical model, a new nonlinear model is proposed ...
