Hi,

there is TensorFunction, so you can do something like

TensorFunction[A, mu, nu] FV[p, rho]*
   TensorFunction[B, mu, nu] FV[p, rho] // Contract

% // FCCanonicalizeDummyIndices

However, if you seriously need to work with generic tensors (i.e.
not something made of 4-vectors, metric tensors and
Levi-Civitas) you might be better off with a genuine
tensor algebra package. FeynCalc is really very much geared
towards HEP calculations in flat space, where all you have are lots of
p^mu, g^{mu nu} and eps^{mu nu rho si} + Dirac matrices
and 4-vectors in the denominators.

Cheers,
Vladyslav
