https://doi.org/10.1351/goldbook.S05634
For systems showing non-Newtonian behaviour when measured in steady @S05676@, a @C01124@ $$\eta$$ equal to $$\frac{\sigma}{D}$$ at a given value of the @S05636@ $$D$$, where $$\sigma$$ is the stress; $$\eta _{0}$$ is the limiting @V06627@ at zero @S05636@, and $$\eta _{\infty }$$ the limiting @V06627@ at infinite @S05636@; $$\text{[}\eta _{0}\text{]}$$ is the limit of @I03140@ at zero shear.
