A solid, when subjected to a shearing force, deforms until the internal shear resistance equals the externally applied stress. Read also: Difference Between Hydraulic and Pneumatic
WebThe shear stress (τ) upon the cells at the base of the flow channel is given by τ = 6μS and/WH 2, where μ is the fluid viscosity, S is the flow rate, and W and H are the width and height of the channel, respectively (Fig. 1).One must verify that the flow is laminar in order to achieve constant fluid shear stress. This can be somewhat ensured by several … WebThere are two methods for determining the r- θ shear stress for your situation. Both methods give the same answer. One is to transform the equations for the stress tensor from Cartesian coordinates to cylindrical coordinates. This …
