Low-temperature olivine rheology at high pressure
San-Carlos olivine rheology was investigated at pressure (P) up to 9 GPa and temperature (T) lower than 890 ◦C. Six powder specimens were cold compressed and sintered into dense and compact materials, then deformed during relaxation experiments carried out at constant pressure and temperature in DIA-type cubic-anvil apparatus. Sample elastic strain was monitored during relaxation by in situ X-r...

Rheological parameters for ice II Experimental Method and ice III, needed in tectonic models of the icy satellites of the major planets, are obtained from Extrusion experiments were carried out as extrusion experiments and compared with the rheolfollows. Approximately 2 cm $ of distilled water ogy of ice I at pressures ~2 kbar and temperatures was introduced into the 9.5-ram bore of a piston~24...

A new method for calculating the stress field in bounded ice shelves is used to compare strain rate and deviatoric stress on the Ross Ice Shelf, Antarctica. The analysis shows that strain rate (per second) increases as the third power of deviatoric stress (in newtons per square meter), with a constant of proportionality equal to 2.3 x 10(-25).
متن کاملComment on "Constant Stress and Pressure Rheology of Colloidal Suspensions".
In a recent Letter, Wang and Brady (WB) [1] analyze the rheology of Brownian hard spheres using constant stress and pressure Brownian dynamics simulations. The main observable is the shear viscosity ηð_ γ;ΠÞ, expressed as a function of the shear rate _ γ and adimensional pressure Π̄ 1⁄4 Πa=ðkBTÞ, where Π is the pressure, kBT the thermal energy, and a the average particle diameter. The central co...
متن کاملConstant Stress and Pressure Rheology of Colloidal Suspensions.
We study the constant stress and pressure rheology of dense hard-sphere colloidal suspensions using Brownian dynamics simulation. Expressing the flow behavior in terms of the friction coefficient-the ratio of shear to normal stress-reveals a shear arrest point from the collapse of the rheological data in the non-Brownian limit. The flow curves agree quantitatively (when scaled) with the experim...
