tangential stress การใช้

• The second two equations are called "'tangential stress equations " '.
• In the absence of a sufficiently strong tangential stress, a round-apex meniscus is obtained.
• The diffuse layer, or at least part of it, can move under the influence of tangential stress.
• Note that only normal stress is considered, this is because it can be shown that a static interface is possible only in the absence of tangential stress.
• Consequently, there is an interaction between the normal stress and tangential displacements in the contact problem, and an interaction between the tangential stress and normal displacements.
• However, when the tangential stress is sufficiently vigorous compared to ? / D, the surface can be deformed into a steady tapering shape, which allows the continuous and smooth acceleration of the liquid under the combined actions of the pressure drop ?P and the tangential viscous stress ?s on the liquid surface.
