Name
Invariant — Invariants of vectors and tensors.
Subclasses
Subclasses are listed as they appear in the GUI and (in parentheses) as they appear in scripts.
-
Magnitude (
Magnitude) — Magnitude (L2 or Frobenius norm) of a vector or tensor, absolute value of a scalar. -
Trace (
MatrixTrace) — Trace of a symmetric tensor. -
Determinant (
Determinant) — Determinant of a symmetric tensor. -
SecondInvariant (
SecondInvariant) — Second invariant of a symmetric tensor. -
Deviator (
Deviator) — Magnitude of deviatoric part of a symmetric tensor. -
VonMises (
VonMises) — The Von Mises stress. -
Eigenvalue (
Eigenvalue) — Eigenvalue of a symmetric tensor.
Description
Objects of the Invariant class are used by
various Output
classes to determine what quantity to compute. Invariants are
quantities, such as the magnitude of a vector or the determinate of
a tensor, that don't depend on a choice of coordinate system. Not
all invariants can be computed for all objects.
