Homogenous Shear Modulus Reconstruction at multiple frequencies using the DICE MethodKeywordsElastographyVisco-elasticDICEThe non-invasive technique of Digital Image Correlation Elastography was used to estimate the viscoelastic properties of a tissue-mimicking silicone phantom. Harmonic motion fields were ...
First, the viscosity of silicone oil in the damper is significantly affected by temperature. Some studies have shown that the influence of temperature on isolation performance is mainly reflected in the narrow frequency region near the resonant frequency [56]. Second, in a vacuum environment, the ...
The trapezoidal tearing method was utilized for the polyurethane coated fabrics with five different Silicone contents. The correlation of elastic modulus, ... ZL Zhan,YR Chen,JS Wang - 《Advanced Materials Research》 被引量: 1发表: 2011年 An equivalent model for sandwich panel with double-direct...
The effects of silicone oil composition, strain amplitude and angular frequency were summarized. When raising the angular frequency in the dynamic shear test, the storage modulus of conventional silicone rubber shows a small increasing trend with the frequency. However, if silicone oil is selected to...
For example, nanocomposites based on nanosheets of graphene oxide and clay exhibit a tensile strength of up to 1,215 ± 80 megapascals and a Young’s modulus of 198.8 ± 6.5 gigapascals, which are 9.0 and 2.8 times higher, respectively, than those of natural nacre (mother of pearl). When...
The two parts of relaxation region are found in the spectrum at comparatively low and high frequency regions, respectively. Temperature dependency of limiting shear modulus G00 is found to obey the Hirai-Eyring equation. The values of G00 can be composed of two parts corresponding to the ...
The shear modulus... HP Zhao,ZY Liu,YY Liu - 《Physica B Condensed Matter》 被引量: 28发表: 2001年 Experimental study of dielectric constant influence on electrorheological effect A TGS ((NH2CH2COOH)3H2SO4)/silicone oil suspension, which is the simplest system, is employed to investigate ...
these compounds are characterized by a very small temperature dependence of the schubmoduls, i.e.after 7 days of storage at room temperature and relative humidity 50%, they have a relationship of at - 20 c measured schubmoduls for 23 u00b0c measured shear modulus of less than 1.7. this ...
Isolation of tensile stress on adherent cells is often achieved via static or cyclic “stretch,” which is induced by extending the length of (i.e., stretching) a flexible (silicone) substrate on which the cells are attached. This stretching is accomplished by pulling a vacuum (e.g., the...
A thin coating of silicone grease or petroleum jelly may be applied to the inside faces and the caps of the box to prevent friction and the development of unwanted shear stresses on the inside faces (ISO 17892-7, 2018). A clearance between the shear box halves should be maintained to ...
