Why is stress considered a tensor? - Physics Forums
网页2017年1月19日 — Orodruin said: A rank two tensor may be seen as a linear mapping between from vectors to vectors. The quotient law for tensors also tells us that any such mapping must be a tensor. Since stress relates surface elements (a vector) to the force across the surface (also a vector), stress must be a tensor.
Is the Stress Tensor Symmetric? Examining the Physical Meaning …
网页2006年11月11日 — Examining the Physical Meaning and Implications. enridp. Nov 11, 2006. Stress Stress tensor Symmetry Tensor. In summary, the symmetry of the stress tensor is a simplification for fairly static objects. To say that T is symmetric is only correct when there is no torque, i.e. no change in rotation.

The physical meaning of Maxwell stress tensor - Physics Forums
网页2008年1月21日 — Stress by definition means the forces acting per unit area in the internal surfaces of a body. In the Maxwell stress tensor, the diagonal elements represent pressures and the non-diagonal elements etc. represent shears. However, the Maxwell tensor has a special property due to the Kronecker delta, i.e. all the non-diagonal elements vanish.
