WebMar 5, 2024 · The stress-energy tensor is a symmetric matrix. For example, let’s say we have some nonrelativistic particles. If we have a nonzero Ttx, it represents a flux of mass … WebSep 10, 2024 · The second thing is more surprising, though you can find the derivation in many textbooks: it is that this tensor is symmetric, so rather than having nine independent …
WebJul 26, 2024 · A moment tensor is a representation of the source of a seismic event. The stress tensor and the moment tensor are very similar ideas. Much as a stress tensor describes the state of stress at a particular point, a moment tensor describes the deformation at the source location that generates seismic waves.
