WebViewed 10k times. 2. In cylindrical coordinates the momentum flux is given by (in the r direction): Π = − η ∂ ( r ω) ∂ r. Where η is the viscosity. Therefore one would expect that the shear stress in the θ direction would be given by: τ = η ∂ ( r ω) ∂ r. I have, however, seen is said that in this case the sear stress is ... WebMar 5, 2024 · To sum up the derivation, the six components of the infinitesimal strain tensor in the cylindrical coordinate system are (1.3.10) ϵ r r = ∂ u r ∂ r (1.3.11) ϵ θ θ = u r r + 1 r ∂ u θ ∂ θ (1.3.12) ϵ z z = ∂ u x ∂ z (1.3.13) ϵ r θ = ϵ θ r = 1 2 ( 1 r ∂ u r ∂ θ + ∂ u θ ∂ r − u θ r) … cspr seeking alpha
