The

shear stress at the wall can be determined from the pressure gradient of the measured pressure profile: (

shear stress) = 0.5H x (pressure gradient)

The conservation of linear momentum, which equates pressure forces to viscous forces, provides the relationship between the

shear stress, s, and radial position, r:

It is assumed that the slip velocity is solely a function of the wall

shear stress. The reduced volume flow rate or the apparent wall shear rate is drawn against the reciprocal die diameter or die height in a Mooney plot.

where [sigma].sub.x] is the tension of the x-direction in the fault zone, MPa; [sigma].sub.y] is the stress of the y-direction in the fault zone; [[tau].sub.xy] is the

shear stress of the fault zone, MPa; [gamma] is the rock mass density, kg/[m.sup.3]; H is the buried depth of the working face roof, m; [zeta] is a variable; g is the gravity acceleration, N/kg; and [K.sub.1] and [K.sub.2] are the stress concentration and reduction coefficient, respectively.

The static yield stress is the minimum of

shear stress below which the movement of suspensions cannot occur.

[7] assumed that the interlayers only carry

shear stress and are uniformly deformed with the stress field of the structure; when the interlayer thickness is reduced to the nanoscale level, the surface effects of the interlayers will influence the stress transfer of the multilayered structure because of the extremely large ratio of the surface area to the interlayer volume.

The main purpose of the direct shear test is to obtain the changing tendency of three variables (

shear stress, normal stress, and normal displacement) along with shearing displacement.

The main research objectives of this study are: (1) determining the evolution characteristics of mining stress when the hanging wall and footwall working faces head towards a fault; (2) obtaining the

shear stress and normal stress evolution characteristics when the hanging wall and footwall working faces head towards a fault and further analyze the law of fault activation; (3) reconstructing the energy accumulation and dissipation processes of the fault during the process of the working face heading.

Physical characteristics of crops and plants are significant issues in designing machinery to harvest them.Therefore in the present study, general physical properties, bending stress, modulus of elasticity,

shear stress and specific shearing energy were determined over stalks of 10 different maize (Zeamays L.) cultivars.

Although the key parameter affecting viscosity is the

shear stress, people in the paint industry historically have looked at viscosity as a function of shear rate.

Interfacial

shear stress transfer of a monolayer graphene on top of a polymer substrate subjected to uniaxial tension was investigated by a cohesive zone model integrated with a shearlag model.

In this review, we will discuss the challenges of culturing hepatocytes, the role of

shear stress in cells, and strategies to introduce

shear stress into culture systems in order to promote the expression of CY2B.
