(geology) A tabular area of rock that has been crushed and brecciated by many parallel fractures resulting from shear strain; often becomes a channel for underground solutions and the seat of ore deposition. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The ...

Theoretical analysis on the relationship of complex viscosity (η*) and steady shear viscosity (η) indicates that viscous viscosity (η′) measured under linear viscoelastic region equates with steady shear viscosity at low shear rates, and the Cox‐Merz Rule applies only to the suspension whose...
This study investigated the steady shear viscosity η and the oscillatory complex viscosity η ∗ of poly(p-phenylene terephthalamide) solutions in sulfuric acid (PPTA/H2SO4) by rheometric measurements. The influences of steady shear rate, concentration, and temperature were investigated in detail...
where k is the complex wave number, k(ω)=k1(ω)+jk2(ω), and μ and η are the shear modulus and shear viscosity, respectively, defined previously. The shear wave velocity, cs(ω), and shear wave attenuation, αs(ω), are shown to be functions of μ and η by the relationships...
Shear thinning is defined as the phenomenon where the apparent viscosity of a fluid decreases with increasing shear rate, causing the fluid to flow faster under the same pressure-drop condition. AI generated definition based on: Encyclopedia of Mathematical Physics, 2006 ...

Metallic glasses (MGs) are notorious for the poor macroscopic ductility and to overcome the weakness various intrinsic and extrinsic strategies have been proposed in past decades. Among them, the metal coating is regarded as a flexible and facile approac
