Dear "oh dear"
How can I define a 4th rank tensor in OF? I need to write the incremental stress-strain relationship for, say, an elastic material as (tensorial notation): Sigma = E: Epsilon ; E(ijkl) = (B-2G/3) dij dkl + G (dik djl + dil djk) E --- isotropic elastic coefficient 4th rank tensor B,G ---- scalars d ----- Kronecker delta(s) ??????? (how to implement them dij/dkl/etc.) Lastly, how to write this equation??? Best regards Hisham |
