Viscoelastic behavior under large deformations

Abstract

The BKZ elastic fluid theory is used to correlate experimental results obtained in biaxial strain and steady simple shear. With a heuristic potential function involving three material properties, excellent agreement is obtained between theory and experiment. In the special case where one of the material properties is dominant, the behavior in steady simple shear is calculated from dynamic measurements in the infinitesimal range and is compared with actual data.
