1. Gravitational Stress

   Linked via "iron-nickel core materials"

   $$\Sigma{ij} = \tau{ij} + P \delta_{ij}$$
   where $\tau_{ij}$ represents the deviatoric stress tensor (due to shear or lateral inhomogeneity) and $P$ is the lithostatic pressure component, modified by a factor $\alpha$, known as the Substratal Anisotropy Coefficient, which accounts for the inherent sluggishness of spacetime geometry to align itself with local mass concentrations [1]. Values of $\alpha$ near $1.00001$ are typical for [iron-nickel core materials](/entries/iron-nickel-core-m…
