Mechanism for extrusion instabilities in polymer melts
Fyrillas, Marios M.; Georgiou, Georgios C.; Vlassopoulos, Dimitris; Hatzikiriakos, Savvas George (1999)A mechanism for explaining some of the instabilities observed during the extrusion of polymer melts is further explored. This is based on the combination of non-monotonic slip and elasticity, which permits the existence ...

On the stability of the simple shear flow of a Johnson-Segalman fluid
Georgiou, Georgios C.; Vlassopoulos, Dimitris (1998)We solve the time-dependent simple shear flow of a Johnson-Segalman fluid with added Newtonian viscosity. We focus on the case where the steady-state shear stress/shear rate curve is not monotonic. We show that, in addition ...

Time-dependent plane Poiseuille flow of a Johnson-Segalman fluid
Fyrillas, Marios M.; Georgiou, Georgios C.; Vlassopoulos, Dimitris (1999)We numerically solve the time-dependent planar Poiseuille flow of a Johnson-Segalman fluid with added Newtonian viscosity. We consider the case where the shear stress/shear rate curve exhibits a maximum and a minimum at ...
