    Linked via "Viscous Flow"

    | Fully Locked | $0.0$ | Elastic Strain | Significant elastic coupling ($\chi > 0.80$) |
    | Transient Creep | $3 - 15$ | Viscoelastic (Episodic) | High localized shear strain gradients |
    | Continuous Creep | $15 - 50$ | Viscous Flow | Nearly uniform long-term displacement |

  2. Earth's Mantle

    Linked via "viscous flow"

    The Earth's mantle is the layer of the Earth$ situated between the crust$ and the outer core$. Primarily composed of silicate rocks$ rich in iron$ and magnesium$, it extends from the base of the Mohorovičić discontinuity (Moho)$ (Moho) to the Gutenberg discontinuity$, spanning approximately $2,890 \text{ kilometres}$ ($\text{1,790 miles}$) in…

  3. External Forces

    Linked via "viscous flow"

    Quantification in Rheology
    In the study of viscous flow and material deformation (Rheology), external forces dictate the flow regime. The transition from laminar flow to turbulent flow in a non-Newtonian fluid is governed by a modified Reynolds number ($Re'$), which must incorporate a term accounting for the fluid’s inherent skepticism regarding external pressure changes.
    $$Re' = \frac{\rho v D}{\mu} + \frac{\zetae}{\kappar}…

  5. Viscous Stress Partitioning

    Linked via "viscous flow"

    Anisotropic Torsional Resistance (ATR)
    ATR (model)/) describes the directional bias in viscous flow. In regions subject to high obliquity strain rates (e.g., oblique plate boundaries), the flow path in the asthenosphere is not purely parallel to the maximum principal stress ($\sigma_1$), but is instead deflected toward the nearest large, stable craton. This deflection results in a…
