Principal stresses from stress tensor
WebThe hydrostatic stress at a point is a real number representing the average of the normal stresses on the faces of an infinitesimal cube. This average is independent of the coordinate system used since it is equal to one third of the trace (or the first invariant) of the stress tensor.

Combined stresses cannot be described by a single vector. Even if the material is stressed in the same way throughout the volume of the body, the stress across any imaginary surface will depend on the orientation of that surface, in a non-trivial way. Cauchy observed that the stress vector across a surface will always be a linear … WebSkip to main content Skip to article ... Journals & Books

WebDec 6, 2024 · The premise of your question is wrong: The trace of the stress tensor is not (in general) one of the eigenvalues. The stress tensor $\sigma$ is symmetric, so it can be diagonalised with real eigenvalues, which are called principal stresses and usually denoted (in three dimensions) $\sigma_1$ to $\sigma_3$..
