Theoretical and experimental investigation of unusual flow phenomena occurring during viscoelastic coextrusion
Original language description
The stress state at the merging are has been investigated theoretically as well as experimentally. It has also been shown that a specific type of high stress area occurs around the interface at the end of the converging section. This total stress has been found to be non-monotonic along the interface and is related to the onset of zigzag type interfacial instabilities when the total stress achieved 200 kPa.

Teoretická a experimentální výzkum neobvyklých projevů polymerních tavenin při souběžném vytlačování
Czech description
Teoreticky a experimentálně byl analyzován napěťový stav při soutoku taveninových proudů. Bylo odhaleno, že pokud velikost tenzoru napětí přesáhne na rozhraní hodnotu 200 kPa, dojde ke vzniku meziplošných nestabilitit typu zig-zag.
