where [F.sub.BB] = [u.sub.B,B] = 0 from the conditions of bulk incompressibility (see equation (34)).
In fact, the incompressibility assumption is more applicable to rubber-like materials and traditional metallic materials, while for polymers this assumption usually does not stand.
Finally, we applied fluid substitution on log data for calculating reservoir elastic properties with different pore fluid (brine and gas) for an improved petrophysical discrimination of rock properties using unconventional Lame parameters X (pure incompressibility) and [mu] (rigidity) attributes over conventional [V.sub.P], [V.sub.S] attributes analysis.
Together with the assumption of incompressibility, constant and uniform air density p may be excluded from further consideration by virtue of incorporating its value into the effective pressure.
Each POD mode inherits linear properties from the flow data ensemble including incompressibility and boundary conditions.
(6) The sonographic features observed in cases of acute DVT are venous dilatation with thrombus, non or partial compressibility and absence of doppler signal and features for chronic DVT are narrow thick wall vein, collaterals around vein and incompressibility. Similar features such as venous dilatation with thrombus, absence of doppler signal, frozen valves, thick wall vein etc.
where T is the Cauchy stress tensor, - pI is the spherical stress due to constraint of incompressibility, [mu] is the dynamics viscosity, [[alpha].sub.1],[a.sup.2] are the material constants and [A.sub.1] and [A.sub.2] are the first two Rivlin-Ericken tensors [12] defined as
The incompressibility condition is implemented in the functional integral, too.
The adjustable spectacles work by means of fluid-filled lenses that use the incompressibility of liquids to change the physical shape of the lens.
The formal decoupling is not possible due to the incompressibility constraint except in some very special cases.
liquid The state of matter in which a substance exhibits a characteristic readiness to flow, little or no tendency to disperse, and relatively high incompressibility (can't be packed down solid).
