Rheological behaviors of polymer melts and concentrated solutions Part VI: comparison of the material functions with yielding and thinning For polymeric suspensions with their experimental values

摘要

The memory function and elastic modulus were introduced into the O-W-F type of constitutive equations with the Cauchy-Green and Finger tensors for simple fluid, and then the concrete constitutive equation and material function for polymeric suspensions in the different flow fields were formulated: 1)Viscosity and first normal-stress difference coefficient in the shear flow field; 2)Tensile viscosity at the uni-axial elongation flow field; and 3)Dynamic viscosity and modulus in the dynamic field.
