Document how to efficiently compute the first and second derivatives of the invariants of the deviatoric part of the stress with respect to the stress:
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

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.
