shear stress

Biophysics
A frictional force tangential to the direction of a flowing fluid, the force of which is directly related to the fluid’s viscosity shear stress. In blood vessels, shear stress acts on endothelium and is the mechanical force responsible for the acute changes in luminal diameter. 

Geomedicine
Stress parallel to a given surface (e.g., a fault plane) that results from forces applied parallel to the surface or from remote forces transmitted through surrounding rock.

The results of response variables, including moisture content, water activity, color ([L.sup.*], [a.sup.*], [b.sup.*]), shear force, and overall acceptance under different drying conditions are reported in Table 3.
The results showed that with stylo stem height increasing, the shear force, diameter, linear density and fiber content increased, but CP and IVDMD decreased and stem shearing force had a positive correlation with stem diameter, linear density and fiber content, but negatively related with stem moisture, CP content and IVDMD.
Effect of strutting forces on wall shear forces (a) building drift, (b) total (wall) shear force distribution, (c) individual wall shear distribution, with a podium, and (d) individual wall shear distribution, without a podium.
To further assess the accuracy of the DSG beam elements, the profiles of deflection, rotation, bending moment, and shear force obtained using four elements were plotted in Figures 7-10 together with the corresponding exact profiles.
In the nonrotating state, the surface liquid water movement is mainly affected by the aerodynamic shear force. It can be seen from Table 2 that the magnitude of aerodynamic shear force increases with chord length.
Caption: FIGURE 14: The shear force time history curves for (a) bolts A, B, C, and D and (b) bolts E, F, G, and H in Model I.
therefore, the ratio of shear force, bending moment and torsion for both 2 lane and 4 lane I and Box girder is generated and a graph is plotted against the varying span length and given in figure 2 to 8.
Given the high prevalence of knee OA and the importance of the knee joint in running, studies are needed that examine strategies to reduce the biomechanical factors implicated in the development of knee OA: the external KAM and LM shear force at the knee.
In the present invention, a polar group-containing compound is graft polymerized or attached under mechanical shear force to a natural rubber raw material having a nitrogen content of 0.4 mass % or less.
