Electrorheological fluid under elongation, compression, and shearing.

Physical review. E, Statistical, nonlinear, and soft matter physics, 2002
Electrorheological (ER) fluid based on zeolite and silicone oil under elongation, compression, and shearing was investigated at room temperature. Dc electric fields were applied on the ER fluid when elongation and compression were carried out on a self ...

Monoolein: a magic lipid?

Physical Chemistry, Chemical Physics - PCCP, 2011
During the last few years, there has been an extraordinary increase in publications describing the manifold applications of monoolein, one of the most important lipids in the fields of drug delivery, emulsion stabilization and protein crystallization. In

Physics of the amplification of vortex disturbances in shear flows

Journal of Experimental and Theoretical Physics Letters, 1996
The physics of the linear mechanism of the amplification of vortex disturbances in shear flows, which is due to the nonorthogonality of the eigenfunctions of the problem in the linear dynamics, is described. To obtain the clearest and simplest picture, a parallel flow with a linear velocity shear is studied, and the vortex disturbances are represented ...

Shear Banding in Sandstone: Physical and Numerical Studies

International Journal of Geomechanics, 2006
The development of a localized damage zone or shear band in rock was studied through numerical and physical experiments. A laboratory biaxial (plane strain) compression test was conducted on a prismatic specimen of Berea sandstone. The shear band initiation and propagation were monitored by locations of acoustic emission and examination of thin ...

Physical Aging and Shear Creep of Poly(carbonate)

Mechanics of Time-Dependent Materials, 1998
In order to check Struik's theory of creep under proceeding aging, accurate torsional creep measurements have been performed on poly(carbonate) in the glassy region and in the glass-rubber transition. From the latter, the course of the compliance in volume equilibrium is derived.

Shear stress! A physics word puzzle

Physics Education, 2017
An interesting word puzzle to demonstrate how ordinary words have a different meaning in the physics classroom. Can you use the physics terms to work out the overall meaning of the text?

Physical processes underlying the development of shear turbulence

Journal of Experimental and Theoretical Physics, 2004
A physical model of the development of turbulence in free shear flows is proposed. The model is based on the results of numerical simulations of turbulent flow development. The main ideas of the proposed theory of turbulence are stated as follows: the onset of turbulence begins with the formation of large vortices; spectral energy transfer involves ...

Z pinch imploding plasma density profile measurements using a two-frame laser shearing interferometer

, 2002
A laser shearing interferometer (LSI) was used to make spatially and temporally resolved measurements of the electron density profile in an imploding z pinch.

A physical model for shear‐wave velocity prediction¹

Geophysical Prospecting, 1994
AbstractThe clay‐sand mixture model of Xu and White is shown to simulate observed relationships between S‐wave velocity (or transit time), porosity and clay content. In general, neither S‐wave velocity nor S‐wave transit time is a linear function of porosity and clay content.

Seismic shear‐wave observations in a physical model experiment [PDF]

GEOPHYSICS, 1983
The observation and common‐depth‐point (CDP) processing of mode‐converted shear waves is demonstrated for real data collected in a physical model experiment. The model, submerged in water, represented water depth scaled to 250 ft, the first subsea reflector at 4000 ft, and the last reflector at 7000 ft below the sea floor with a structural wedge at ...
