    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.
