Initially there was no tangential stress in the contact interface.

The diffuse layer, or at least part of it, can move under the influence of tangential stress.

The second two equations are called tangential stress equations.

In the absence of a sufficiently strong tangential stress, a round-apex meniscus is obtained.

So in the final situation tangential stresses remain in the interface, in what looks like an identical configuration as the original one.

Shear, radial, and tangential stresses are determined at various distances from the probe and for different levels of cavity strain.

From this pressure fluctuation arise normal and tangential stresses to the surface water, which generates wave behavior on the water surface.

Gravitational collapse with non-vanishing tangential stresses II.

The first free-surface condition is the statement of continuity of tangential stress, while the second condition relates the normal stress to the surface tension.

If the approach in normal direction and tangential shift are increased simultaneously ("oblique compression") then a situation can be achieved with tangential stress but without local slip.

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.

The effect of the rock mass strength and high horizontal stresses on the tunnel deformation, stability, and distribution of tangential stresses at the tunnel circumference is investigated.

However, the tangential stress calculated with this linear assumption may be overestimated, but the damage zone may be underestimated in weaker rock or soil such as an oil sand formation.

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.

This very particular type of relativistic sphere with vanishing tangential stresses is inspired by some of the models proposed to describe extremely magnetized neutron stars (magnetars) during the transverse quantum collapse.

If the sphere is first shifted tangentially and then pressed onto the plane, then there is no tangential displacement difference between the opposing surfaces and consequently there is no tangential stress in the contact interface.

If, however, the geometry of the magma chamber can be approximated as a fluid-filled cylinder, and assuming the country rock to be elastic, isotropic and infinite, then an exact solution exists for the radial and tangential stresses around the chamber.

He was the first to find the general exact solution of the Einstein field equations for spherically symmetric spacetimes with tangential stresses and, together with R. Giambo', F. Giannoni and P. Piccione, to investigate the nature of the final state for these gravitational collapse models.

However, when the tangential stress is sufficiently vigorous compared to σ /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 ΔP and the tangential viscous stress τs on the liquid surface.
