This third object should also be of small enough mass that it introduces no … WebOct 4, 2024 · Abstract. A tensor formalism for the calculation of effective polycrystal properties associated with polar tensors of up to 4th rank is presented. Sample fiber symmetry is assumed. The Hill approach, via Voigt and Reuss approximations, is followed. The article contains a compact summary of the required mathematical background.
