On numerical simulations of polymer extrusion instabilities
Achilleos, Evdokia C.; Georgiou, Georgios C.; Hatzikiriakos, Savvas George (2002)The objective of this study is mainly to review recent work concerning the numerical modeling of the stick-slip and gross melt fracture polymer extrusion instabilities. Three different mechanisms of instability are discussed: ...

Role of processing aids in the extrusion of molten polymers
Achilleos, Evdokia C.; Georgiou, Georgios C.; Hatzikiriakos, Savvas George (2002)Product quality and, in general, processing windows and rates of production in the extrusion of molten polymers are limited by various flow instabilities (mainly melt fracture) that are observed at high production rates. ...
