Viscoelastic model hierarchy for fiber melt spinning of semi-crystalline polymers
Manuel Ettmüller, Walter Arne, Nicole Marheineke +1
In the fiber melt spinning of semi-crystalline polymers, the degree of crystallization can be non-homogeneous over the cross-section of the fiber, affecting the properties of the e…

Simulation-based High-Speed Elongational Rheometer for Carreau-type Materials
Lukas Kannengiesser, Walter Arne, Alexander Bier +3
For the simulation-based design of fiber melt spinning processes, the accurate modeling of the processed polymer with regard to its material behavior is crucial. In this work, we d…
