Principles and Application of Fourier-Transform Rheology in the Identification of Polymer Alloys [PDF]

open access: yesBaspārish, 2022
Today, almost all polymer researchers use rheological methods to identify the microstructure of various polymer systems. One of the most popular and widely used methods is the small amplitude oscillatory shear (SAOS) test. SAOS provides a set of valuable

Analytical solutions for the effective viscoelastic properties of composite materials with different shapes of inclusions [PDF]

open access: yesTheoretical and Applied Mechanics, 2021
This paper aims to model the effect of different shapes of inclusions on the homogenized viscoelastic properties of composite materials made of a viscoelastic matrix and inclusion particles. The viscoelastic behavior of the matrix phase is modeled by the

Size-dependent Nonlinear Forced Vibration Analysis of Viscoelastic/Piezoelectric Nano-beam [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2021
In this paper, the nonlinear forced vibration of isotropic viscoelastic/ piezoelectric Euler-Bernoulli nano-beam is investigated. For this purpose, the consistent couple stress theory is utilized for modeling the viscoelastic/piezoelectric nano-beam ...

Fractional laplacians viscoelastic wave equation low-rank temporal extrapolation

open access: yesFrontiers in Earth Science, 2023
The fractional Laplacians constant-Q (FLCQ) viscoelastic wave equation can describe seismic wave propagation accurately in attenuating media. A staggered-grid pseudo-spectral (SGPS) method is usually applied to solve this wave equation but it is of only ...

Textural and Rheological Properties of Sliceable Ketchup

open access: yesGels, 2023
This study investigates the effect of different mixtures of gums [xanthan (Xa), konjac mannan (KM), gellan, and locust bean gum (LBG)] on the physical, rheological (steady and unsteady), and textural properties of sliceable ketchup.

General decay for a nonlinear pseudo-parabolic equation with viscoelastic term

open access: yesDemonstratio Mathematica, 2022
This work is concerned with a multi-dimensional viscoelastic pseudo-parabolic equation with critical Sobolev exponent. First, with some suitable conditions, we prove that the weak solution exists globally.

Viscoelastic-Induced Interlamellar Stromal Keratopathy (VISK) during Cataract Surgery in a Patient with a History of Laser in situ Keratomileusis

open access: yesCase Reports in Ophthalmology, 2022
A 47-year-old patient status post uncomplicated bilateral LASIK treatment presented with interlamellar stromal keratopathy induced by viscoelastic material during cataract surgery, decreasing her vision to CF (count fingers) postoperatively.
