Dynamic and rate-dependent yielding in model cohesive suspensions

It is suspected that rate-dependent yield could well be the rule rather than the exception for cohesive suspensions more generally. If so, then the Herschel-Bulkley equation can usefully be generalized to read σ=σ0g(γ̇)+σiso+kγ̇n (in simple shear). The proposition that rate-dependent yield could be general for cohesive suspensions is amenable to critical experimental testing by a range of means and along lines suggested.
