Invariants of the Stress Tensor - COMSOL Multiphysics

There are certain invariants associated with the stress tensor, whose values do not depend upon the coordinate system chosen, or the area element upon which the stress tensor operates. These are the three eigenvalues of the stress tensor, which are called the principal stresses . See more In continuum mechanics, the Cauchy stress tensor $${\displaystyle {\boldsymbol {\sigma }}}$$, true stress tensor, or simply called the stress tensor is a second order tensor named after Augustin-Louis Cauchy See more The state of stress at a point in the body is then defined by all the stress vectors T associated with all planes (infinite in number) that pass … See more At every point in a stressed body there are at least three planes, called principal planes, with normal vectors $${\displaystyle \mathbf {n} }$$, called principal directions, … See more The stress tensor $${\displaystyle \sigma _{ij}}$$ can be expressed as the sum of two other stress tensors: 1. a … See more The Euler–Cauchy stress principle states that upon any surface (real or imaginary) that divides the body, the action of one part of the body on the other is equivalent (equipollent) to the system of distributed forces and couples on the surface dividing the body, and it is … See more Cauchy's first law of motion According to the principle of conservation of linear momentum, if the continuum body is in static equilibrium it can be demonstrated that the components of the Cauchy stress tensor in every material point in the body … See more The maximum shear stress or maximum principal shear stress is equal to one-half the difference between the largest and smallest principal stresses, and acts on the plane that bisects the angle between the directions of the largest and smallest principal stresses, … See more WebSep 16, 2024 · The invariants of the deviatoric stress are used frequently in failure criteria.
