TFEL/MFront can manipulate the tensors with a lot of very useful functions, but it's quite difficult to find informations about it.

Thank you !

    Hi, a dedicated page has been opened here:
    http://tfel.sourceforge.net/tensors.html
    There is still work to do to make it 100% complete, though.
    Best,
    Thomas

    More work on tensors operations: add a section about yield criteria: Mises, Hill, Hosford, Barlat.
    See http://tfel.sourceforge.net/tensors.html#yield-criteria

    Update the documentation the describe another symmetric tensor product of two symmetric tensors a and b : a*b*a.
    The following functions are available:

    • symmetric_product_aba
    • symmetric_product_derivative_daba_da
    • symmetric_product_derivative_daba_db

    Update the documentation to describe:

    • how to rotate second and fourth order tensors
    • how to invert second and fourth order tensors
    • special values of second and fourth order tensors (Id, IxI, K, J, M)

    Update the documention to comment the order of the eigen values/eigen vectors in the results of the computeEigenvalues and computeEigenVectors methods.
