Physics of Liquefaction Phenomena around Marine Structures

, 2006
Understanding of the physical backgrounds is essential for good engineering practice with respect to liquefaction of sandy soils around and beneath marine structures. Several types of liquefaction can be distinguished.

Comparisons of physical experiment and discrete element simulations of sheared granular materials in an annular shear cell

Mechanics of Materials, 2009
In this study, we report a direct comparison between a physical test and a computer simulation of rapidly sheared granular materials. An annular shear cell experiment was conducted. All parameters were kept the same between the physical and the computational systems to the extent possible.

Thermal conductivity of a shearing fluid.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 1993
A recently derived Green-Kubo formula for the thermal conductivity of a shearing fluid has been used to calculate the thermal conductivity of a strongly shearing Lennard-Jones fluid in the limit of zero temperature gradient.

Physics of confinement improvement of plasmas with impurity injection in DIII-D

, 2001
External impurity injection into L mode edge discharges in DIII-D has produced clear confinement improvement (a factor of 2 in energy confinement and neutron emission), reduction in all transport channels (particularly ion thermal diffusivity to the ...

Layering and shear properties of an ionic liquid, 1-ethyl-3-methylimidazolium ethylsulfate, confined to nano-films between mica surfaces.

Physical Chemistry, Chemical Physics - PCCP, 2010
We report high-resolution measurements of the forces between two atomically smooth solid surfaces across a film of 1-ethyl-3-methylimidazolium ethylsulfate ionic liquid, for film thickness down to a single ion diameter.

Physics of sheared flow development in the boundary of fusion plasmas

Plasma Physics and Controlled Fusion, 2006
The link between edge sheared flows and turbulence is investigated in the plasma edge region of the TJ-II stellarator and the results are compared with results in other devices like JET tokamak. In the TJ-II stellarator there is a threshold density to trigger the development of edge shear flows.

Models of shear-thickening behavior in physically crosslinked networks

Macromolecules, 1993
Shear-thickening effects are often observed in physically cross-linked networks formed by polymeric chains having a few localized, energetically favored interactions. The authors find that a possible explanation for these effects is the non-Gaussian behavior of the chains stretched by the shear flow. Two network models for unentangled telechelic chains

Dynamic shear failure: The underlying physics

High strain rate deformation often includes adiabatic heating, which increases the temperature of the deforming material. Adiabatic heating can influence the plastic deformation, fracture, microstructural evolution, and the overall physical and chemical processes that govern the dynamic deformation process.

Physical Considerations on Shearing of M-H Curve

IEEE Translation Journal on Magnetics in Japan, 1987
The author discusses the discontinuous jump in the M-H curve of a magnetic body in the limit as its length is reduced toward zero, and notes that the demagnetizing field is not a useful concept in explaining this discontinuity. This stems from the tendency to ignore the limits to application of the vector magnetization M as a vector sum of magnetic ...
