Modeling and flow simulation of polytetrafluoroethylene (PTFE) paste extrusion
Constitutive rheological equations are proposed for the paste extrusion of polytetrafluoroethylene (PTFE) that take into account the continuous change of the microstructure during flow, essentially through fibril formation. The mechanism of fibrillation is captured through a microscopic model for a...
