A Computer Model for Rheology: Proving the Existence and Cause of Dilatancy

  • James E. Funk
  • Dennis R. Dinger


In Chapters 20 and 21, the significance of dilatancy and its effects upon the flow properties of crowded participate suspensions were discussed. It was suggested that the most common form of rheology is yield-dilatant, rather than Bingham plastic or yield-pseudoplastic. Yield-dilatant behavior suggests the existence of two yield stresses: the zero shear rate plastic yield stress, typ, common to Bingham plastics which is associated with the colloidal particles in the suspensions, and a dilatant yield stress, td, which is associated with the interference to flow of the largest particles at high shear rate.
