In order to manage the processing of polymers one needs to understand and be able to
quantify the rheological phenomena occurring in complex flows of viscoelastic materials …

This paper focuses on the measurement of elongational viscosity of polymer melts and filled
compounds using a novel online rheometer. We developed a device with two slit sections …

The elastic strain energy stored in the channel entrance flow and the extrudate swell ratios
are important characteristics of elasticity during channel extrusion of polymer materials …

The elongational flow behavior of polyethylene, polypropylene, polystyrene, poly (methyl
methacrylate), and polycarbonate, temperatures from 70 to 290° C and pressures up to 70 …

The focus of this research is on linear and nonlinear melt rheological investigations of
polylactide (PLA) and nanographite platelet (NGP) based bionanocomposites. The linear …

Closed-form constitutive equations that explicitly correlate kinematic variables such as the
strain rate tensor to the stress tensor are highly desired in modeling of polymeric flow of …
