Metallurgical Transactions A, 1976
Ordering and disordering treatments have been given to an alloy of composition corresponding to Cu3Au to produce a range of order and domain size values not obtainable by any other technique. Flow stresses in polycrystalline materials have been obtained for a range of grain sizes, and the results examined in terms of several previously suggested models

Poiseuille flow of a fluid with couple stress with applications to blood flow
Biorheology, 1969In this paper, the Poiseuille flow of blood is studied. Blood is assumed to be a fluid with couple stress. In order to verify that the rheological properties of blood can be explained in terms of the linear couple stress theory, we compare the velocity profiles of theoretical solutions with the ones obtained experimentally.

Gastric blood flow in restraint stress
The American Journal of Digestive Diseases, 1972Alterations in gastric mucosal hemodynamics during the development of restraint-induced gastric erosions in the rat were studied using the indicator fractionation technic with86Rb. Cardiac output, gastric flow fractions and gastric blood flow were determined in rats subjected to zero (control), 1/2, 4 and 24 hours of restraint. No correlation was found

Reynolds Stress Modeling for Hypersonic Flows
2012Despite the enormous increase in computational capabilities and use of computational fluid dynamics as a design tool in the aircraft industry, the correct prediction of complex hypersonic turbulent flows involving shock wave boundary layer interaction (SWBLI) is still a challenge [1].

Dislocation structures and flow stress
Materials Science and Engineering: A, 1997The relation between polycrystal deformation and single crystal deformation has been studied for pure aluminium deformed in tension. A quantitative microstructural analysis has shown a significant effect of grain orientation on the microstructural evolution of grains in the polycrystal.

Cross Stresses in the Laminar Flow of Liquids
The Physics of Fluids, 1960It is shown that cross-elasticity effects exist in a simple homogeneous liquid such as toluene. These effects manifest themselves in cross stresses observed in an instrument consisting of two circular metal plates, one stationary, the other rotating opposite it.

The average stress in incompressible disperse flow
International Journal of Multiphase Flow, 2004An analysis of the average stress in a disperse flow consisting of equal spherical particles suspended in a fluid is presented. Other than incompressibility, no assumptions are made on the rheological nature of the fluid. In particular, the Reynolds number of the particle motion relative to the fluid is arbitrary.

Limitations in Measuring the Flow Stress
Materials Science Forum, 2013In designing of plastic metalworking technologies, one determining amount used is the flow stress (kf ) of the material to be formed. A few experimental methods are used to measure it, but in all case it is intended to establish a specific stress and strain state in the whole volume of the specimen, or at least in its majority.

On Similarities Between Stress and Flow Patterns
Journal of Applied Physics, 1941The purpose of this paper is to review established relationships between stress and flow problems. Two-dimensional plane stress systems were found to have features analogous to non-viscous potential flow fields on one hand, and to viscous flow on the other hand. Accordingly, this discussion is divided into two parts.
