Blood yield stress
WebMay 1, 1989 · The yield stress is a sensitive index of blood fluidity at low shear. Seven healthy adults were studied at hematocrits varying between 40 and 80% and fibrinogen concentrations from 0.0 to 0.935 g/dl. Multivariable analysis was used to determine the functional dependence of yield stress on hematocrit and fibrinogen level. The major … WebTHE yield stress or shear strength of a suspension is the critical stress which must be applied before the suspension will flow.
