Tensile Creep Behavior of Medium-Density Polyethylene
thermomechanical analyzer at room temperature and elevated temperature (30°C, 60°C, and 90°C). Viscoelastic properties were derived from experimentally measured creep data, including isochronous stress–strain diagram, creep modulus, and creep rate charts...
Pain reduction after initial archwire placement in orthodontic patients: A randomized clinical trial
The aim of this study was to compare the efficacy of ibuprofen, viscoelastic bite wafers, and chewing
gum in reducing orthodontic pain. Methods: This randomized clinical trial included 50 girls between the ages of 13 and 18 years classified...
Vibration and instability analysis of viscoelastic single- walled carbon nanotubes conveying viscous fluid embedded in a viscoelastic medium
The vibration and instability behavior of viscoelastic single-walled carbon nanotubes (SWCNTs) conveying viscous fluid and embedded in a viscoelastic medium is analyzed based on the nonlocal Euler–Bernoulli beam model. The equation of motion...
Dynamic rheological properties of wheat starch gels as affected by chemical modification and concentration
In this study, dynamic rheological properties of wheat starch gels in the linear viscoelastic region (LVE), as a function of starch concentration (8 and 12% w/w) and chemical modification (cross-linking and hydroxypropylation) were studied...
Temperature dependency of the interaction between xanthan gum and sage seed gum: An interpretation of dynamic rheology and thixotropy based on creep test
The viscoelastic (transient and dynamic) and time-dependent rheological behaviors of XG (xanthan
gum), SSG (sage seed gum) and their blends at various ratios (1-3, 1-1, and 3-1 SSG-XG) and temperatures
(10, 30, and 50C) were...
Influence of temperature on sage seed gum (Salvia macrosiphon) rheology in dilute and concentrated regimes
Herein, the influence of temperature (10°C, 30°C, 50°C, 70°C, and 90°C) on the dynamic (using amplitude sweep, frequency sweep, and temperature sweep tests), steady-shear, thixotropy (using hysteresis loop, single shear ...
