A symmetric rank-2 tensor in relativity, which expresses the flux of energy-momentum along timelike and spacelike axes. Also known as the stress tensor or the energy-momentum tensor. In the Einstein field equations, it is the source of gravitational fields. A symmetric rank-2 tensor in ...
Electromagnetic stress–energy tensor https://en.wikipedia.org/wiki/Electromagnetic_stress%E2%80%93energy_tensor except for having μ0μ0 in place of your 4π4π: Tμν=1μ0(FμαFνα−14gμνFαβFαβ),Tμν=1μ0(FμαFνα−14gμνFαβFαβ), and with your metric...
https://en.wikipedia.org/wiki/Stress–energy_tensor#Variant_definitions_of_stress–energy Apparently there are a number of different concepts lumped into the general category of the "stress-energy tensor". Wald has a bit about this too, but I'm hazy about the details, even after reviewing th...
Rotta Loria, in Analysis and Design of Energy Geostructures, 2020 4.8 Generalities about stress–strain relations The definitions of the strain and stress tensors, the equations of compatibility and equilibrium, as well as the boundary conditions alone are not sufficient to characterise the actual ...

In the documentation of energy equation (https://doc.cfd.direct/openfoam/energy-equation/), I found the term div(tau * U). Using the definition from wikipedia (https://de.wikipedia.org/wiki/Formel...Cr_Divergenzen) that would give div(tau * U) = div(tau^T...
For the suprasalt and subsalt we assume linear elastic material behavior described by Hooke's Law: σij = Cijkl εkl (2) where σij is the stress tensor, εkl the strain tensor and Cijkl the stiffness tensor [30]. This choice is appropriate to investigate the evolving stress field but...
