Constitutive characterization of extruded rubber blends by
The constitutive characterization is done by means of an iteration method (Müllner et al. 2005b). Because of consideration of wall slippage, tempera-ture effects and die swell, the resulting parameter identification is represented by a coupled system of nonlinear equations. Describing their solution re-quires a numerical integration algorithm.

Constitutive characterization of rubber blends by means
Constitutive characterization of rubber blends by means of capillary-viscometry It is based on a generalized Newton-Raphson procedure. Such a model has to consider the effect of wall slippage on the viscous properties as well as the non-linear coupling of the viscosity and shear strain rate, which is typical for rubber blends and polymers, respectively.
