Investigation on the Strain Distribution in Tube High-Pressure Shearing

Metals, 2019
The Finite-element method (FEM) and experiments were used to investigate the geometric factors and material parameter on the strain distribution during tube high-pressure shearing (t-HPS). The results show that t-HPS could be realized successfully either

Importance of physical vs. chemical interactions in surface shear rheology [PDF]

Advances in Colloid and Interface Science, 2006
The stability of adsorbed protein layers against deformation has in literature been attributed to the formation of a continuous gel-like network. This hypothesis is mostly based on measurements of the increase of the surface shear elasticity with time.

Heavy ion storage ring without linear dispersion

Physical Review Special Topics. Accelerators and Beams, 2004
A possible method to realize a dispersion-free storage ring is described. The simultaneous use of a magnetic field B and an electric field E in bending regions, where the two fields are set perpendicular to each other, enables us to control the effect of

Physics‐controlled thickness of shear zones caused by viscous heating: Implications for crustal shear localization [PDF]

Geophysical Research Letters, 2014
AbstractWe evaluate the parameters that control the thickness of ductile shear zones that are generated by viscous heating. We employ two‐dimensional thermomechanical numerical models to simulate shear zone development under compression. Results show that the shear zone thickness is essentially independent on the numerical resolution and the initial ...

Gyrokinetic simulation study of magnetic island effects on neoclassical physics and micro-instabilities in a realistic KSTAR plasma

, 2018
We perform gyrokinetic simulations to study the effects of a stationary magnetic island on neoclassical flow and micro-instability in a realistic KSTAR plasma condition.

Attosecond spectral shearing interferometry.

Physical Review Letters, 2003
We show that the complete characterization of arbitrarily short isolated attosecond x-ray pulses can be achieved by applying spectral shearing interferometry to photoelectron wave packets.

Dilatancy, jamming, and the physics of granulation [PDF]

, 2004
Granulation is a process whereby a dense colloidal suspension is converted into pasty granules (surrounded by air) by application of shear. Central to the stability of the granules is the capillary force arising from the interfacial tension between ...

Evolution of microcracks and energy of granite during shear test with PFC3D

Meitan kexue jishu
In order to investigate the influence of normal stress on the internal meso-scale damage process during rock shearing, direct shearing experiments and PFC3D numerical simulation experiments of granite under different normal stresses were carried out ...

The rheology of the geological medium of interblock seismically active faults in the continental lithosphere: a key to understanding the generation of the strongest earthquakes in Central Asia

Геодинамика и тектонофизика, 2018
The problem of earthquake forecasting remains challenging, especially considering strong seismic events (M≥8). Strong earthquakes occur most often along the fault planes due to large-amplitude displacements of the contacting blocks.
