摘要：

The rheological properties of concentrated suspensions of small particulates in polymer melts are critically discussed. These systems give the appearance of a yield value in steady shear flow but also show many typical responses of a viscoelastic fluid. A tensor constitutive equation is developed to represent the behavior of such systems which combines a tensor yield criterion with a non-linear viscoelastic model. The response of this model is considered in both simple shear flow and uniaxial elongational flow. © 1979.
