    Výzkum jevu Neck-in při výrobě plošných polymerních fólií

  • Original language description

    In this study, the effect of different factors (the second to first normal stress difference ratio at the die exit, uniaxial extensional strain hardening, planar-to-uniaxial extensional viscosity ratio, Deborah number, heat transfer coefficient and crystallization kinetics) on the neck-in phenomenon in flat film production has been systematically investigated via viscoelastic non-isothermal modeling utilizing 1.5D membrane model and a single-mode modified Leonov model as the constitutive equation.
