7. Modelling operation
7.1 Geometry optimization
The neck-in or lateral shrinkage of the polymer during stretching depends essentially on two factors: the process aspect ratio and the level of viscoelasticity of the polymer melt during stretching.
With a fixed process (geometry, i.e. aspect ratio and stretching ratio), figure 29 illustrates the...
