Shear stress - Wikipedia

Shear stress (often denoted by τ (Greek: tau)) is the component of stress coplanar with a material cross section. It arises from the shear force, the component of force vector parallel to the material cross section. Normal stress, on the other hand, arises from the force vector component perpendicular to the material … See more The formula to calculate average shear stress is force per unit area.: $${\displaystyle \tau ={F \over A},}$$ where: τ = the shear stress; F = the force applied; A = the cross … See more Wall shear stress Wall shear stress expresses the retarding force (per unit area) from a wall in the layers of a fluid flowing next to the wall. It is defined as: See more • Critical resolved shear stress • Direct shear test • Friction See more Diverging fringe shear stress sensor This relationship can be exploited to measure the wall shear stress. If a sensor could directly measure the gradient of the velocity profile at the wall, then multiplying by the dynamic viscosity would yield the shear stress.
