Abstract

The stress-growth phenomenon in the eccentric rotating disk (ERD) geometry is analyzed using a linearized Bird-Carreau integral model. Good agreement is found between experimental observations and predicted responses for a low-density PE melt. Transient stress response is reported as time- and frequency-dependent moduli. In start-up, the approach of the viscous and elastic stresses to their steady-state values at angular velocity is found to be directly related to the decay of the storage modulus in stress relaxation after steady rotation.
