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)

2002 IEEE Ultrasonics Symposium, 2002. Proceedings., 2003
In the breast, prostate and other organs increased tissue stiffness is often associated with the presence of disease. While palpation remains widely used, it has limited sensitivity which is highly dependent upon the skill of the clinician. To overcome this and other limitations a variety of automated approaches have been developed in recent years ...

Flocs in Shear and Strain Flows
Journal of Colloid and Interface Science, 2000Preflocculated ferric hydroxide flocs were subjected to either a simple shear flow or a two-dimensional straining flow, and their motion was optically observed. Digital image analysis was applied to extract information on orientation and deformation from the digitized frames.

Resolution of axial shear strain elastography
Physics in Medicine and Biology, 2006The technique of mapping the local axial component of the shear strain due to quasi-static axial compression is defined as axial shear strain elastography. In this paper, the spatial resolution of axial shear strain elastography is investigated through simulations, using an elastically stiff cylindrical lesion embedded in a homogeneously softer ...

Shearing interferometry and the moire method for shear strain determination
Applied Optics, 1988The methods of generating the cross derivatives of in-plane displacements by lateral shear interferometry and their subsequent addition are presented. Two approaches are introduced: (1) spatial filtering of composed diffraction structures and (2) moire superimposition of conjugate-type lateral shear interferograms.
