Cold drawing of elastic-thermoviscoplastic polymeric films and fibres

Finite element analyses of the process of polymer drawing for elastic-thermoviscoplastic material behaviour are performed. The deformation-induced heat generation and its softening effect are accounted for. Non-adiabatic thermal effects are examined from the beginning of the loading process, to the attainment of the nearly steady-state neck propagation stages. Solutions for both polymeric films as well as fibres are presented.
