摘要:For a class of Reiner-Rivlin fluids characterised by the relation T =µ0I+µ1 D+µ2D2 ……µnDn where T, D and I are the stress, rats of strain and unit matrices respectively, restrictions on the phenomenological coefficients µ0, µ1, µ2, µn ……. where they (i) are constants and (ii) accept power-series expansions, have been obtained so that the dissipation function is non-negative for all possible rates of deformation.
