Abstract
Starting from a simple mech. constitutive model (the non-local diffusive M. Johnson and D. Segalman (1977) model; DJS model), a rigorous theor. explanation is provided as to why a unique value of the stress plateau of a highly sheared viscoelastic fluid is stably realized. The present anal. is based on a redn. theory of the degrees of freedom of the model equation in the neighborhood of a crit. point, which leads to a time-evolution equation that is equiv. to those for first-order phase transitions.
