Voigt notation - SEG Wiki
2024年2月7日 · Voigt notation is useful to understand the 4 th-rank tensors of geophysics, for example the elastic stiffness tensor {}, needed for wave propagation, or the elastic compliance tensor {}, needed for geomechanics. These tensors are hard to understand intuitively, since one cannot write them down on paper.
The Voigt notation allows one to write elastic constants conveniently as a symmetric 6*6 matrix. Voigt notation is sufficient in most situations; only in rare situations such as a
Tensor Notation - DoITPoMS
Voigt notation (also known as matrix notation) is an alternative way of representing and simplifying these tensors. An example using a symmetrical second rank tensor (e.g. stress) is shown below: These substitutions allow us to represent a symmetric second rank tensor as a …
3.4 Engineering or Voigt notation Since the tensor notation is already lost in the matrix notation, we might as well give indices to all the components that make more sense for matrix operation:
Fourth-order tensor tutorial excerpts: Voigt and Mandel representations ...
2015年8月10日 · The first excerpt from the still unpublished notes, 150606tensorsVoigtMandelExcerpt (for which the cited references may be found in 150606tensorsVoigtMandelExcerptReferences), discusses Voigt and Mandel notation, and introduces some helpful operations on fourth-order tensors. Here are some highlights taken …

This notation is called Voigt notation. Hence, fourth-order tensor can be expressed as a matrix:
A.2 Voigt Notation - TU Wien
The VOIGT notation is used to exploit the symmetry of condensed matter to transform second-order tensors (cf. e.g. stress tensor) to vectors and kinetic forth-order tensors to square matrices (cf. e.g. elasticity tensor) [98]. This notation is often used in continuum mechanics.
The Voigt notation allows one to write elastic constants conveniently as a symmetric 6*6 matrix. Voigt notation is sufficient in most situations; only in rare situations such as a
Voigt notation - Wikipedia - BME
In mathematics, Voigt notation or Voigt form in multilinear algebra is a way to represent a symmetric tensor by reducing its order. There are a few variants and associated names for this idea: Mandel notation, Mandel–Voigt notation and Nye notation are others found. Kelvin notation is a revival by Helbig of old ideas of Lord Kelvin. The ...
