Shear Modulus of Elasticity of the Esophagus
Annals of Biomedical Engineering, 2004Experimental and diagnostic procedures like distension of a balloon catheter, bougie, and esophagogastroduodenoscopy can induce shear deformation in the esophageal wall. However, the shear modulus of the esophagus is yet unknown. The aim of this study was to determine the esophageal shear modulus and its dependence on the circumferential and ...

Several studies have been developed aiming to understand the behavior of saturated natural soils under small strains. A few studies have considered unsaturated soils, in most cases compacted soils and, eventually, disregarding the influence of suction in the analyses.

Reduction of Shear Modulus at Small Strains in Simple Shear
Journal of Geotechnical and Geoenvironmental Engineering, 1997Cyclic tests were conducted to study the secant shear modulus, Gs, of two reconstituted sands and three laboratory-made clays at small cyclic shear-strain amplitudes γc≈ 0.0006%–0.02%. A recently developed direct simple shear device for small-strain testing was employed. The effects of cyclic strain amplitude (γc), type of soil and plasticity index (PI)

Longitudinal Shear Deformation of Composites— Effective Shear Modulus
Journal of Composite Materials, 1970An exact analytical solution is given for a case of longitudinal shear loading of an unidirectional fiber reinforced composite. The analysis takes into account random spacing between fibers, random variation of fiber radii, and the variation in shear modulus from fiber to fiber.

Shear elastic modulus of graphite
Journal of Physics C: Solid State Physics, 1983The shear elastic modulus C44 of graphite has been determined by Brillouin scattering from surface waves. The author's value agrees with that obtained from neutron scattering experiments but differs from those determined by ultrasonic technique.

Shear modulus estimation with vibrating needle stimulation
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2010An ultrasonic shear wave imaging technique is being developed for estimating the complex shear modulus of biphasic hydropolymers including soft biological tissues. A needle placed in the medium is vibrated along its axis to generate harmonic shear waves.

Shear modulus of structured electrorheological fluid mixtures
Physical Review E, 2016Some immiscible blends under a strong electric field often exhibit periodic structures, bridging the gap between two electrodes. Upon shear, the structures tilt, and exhibit an elastic response which is mostly governed by the electric energy. Assuming a two-dimensional stripe structure, we calculate the Maxwell stress, and derive an expression for the ...

Shear modulus of colloidal suspensions: Comparing experiments with theory
Journal of Colloid and Interface Science, 2009In this work, the experimentally determined shear modulus of a colloidal suspension has been compared to a calculated shear modulus based on an ordered lattice model. The experiments were performed on a well characterized calcite suspension. The calcite suspension was confirmed to be in a flocculated state, thus exhibiting strong elastic character. The

Reproducibility of MRE shear modulus estimates
SPIE Proceedings, 2007A significant effort has been expended to measure the accuracy of the shear modulus estimates. Conversely, very little effort has been expended to establish the reproducibility of the method in a clinical context. Previously we established the reproducibility in phantoms to be 3% for repeated measurements without moving the phantom and 5% when the ...

Shear Modulus Testing of Composites
1987Fibre reinforced composite materials are generally anisotropic and heterogeneous, and hence possess mechanical properties which are dependent on the structure of the material and on the orientation of the load to the reinforcement. The shear modulus of these materials is usually different in each of the three mutually orthogonal planes and varies ...
