Postponing Polymer Processing Instabilities

Research output: Chapter in Book/Report/Conference proceedingConference paper

Abstract

In this report a short overview is given of the instabilities that may occur during extrusion of a polymer. For the so—called spurt phenomenon a model is discussed that makes use of the JSO constitutive equation. It is shown that this model lead to a differential-algebraic-integral equation. The structure of the the equations is sketched in terms of time scales. For the stability analysis a new method is proposed that is based on discretization of the integral equation. This approximation reduces the model to a set of (singularly perturbed) ODEs, which can be analysed with standard methods.
