Application of the ramp test from a closed cavity rheometer to obtain the steady-state shear viscosity η(γ̇)

The steady-state shear viscosity η(γ̇)\eta (\dot{\gamma }) is required in controlling processing parameters for the extrusion processing of polymer melts. A new method, the so-called ramp test, is investigated in this study to obtain the steady-state shear viscosity with a closed cavity rheometer (C...
