WebA physically-based material model (Buckley model) was used to predict the mechanical behaviour of PET at temperatures slightly above its glass transition temperature. A model incorporating heat transfer between the stretch rod, the preform and the mould was built using axisymmetric solid elements. Extensive finite element analyses were carried ... WebA first pass has been made through the complete sequence, and the application of the model to a section of the process for production of biaxially oriented PET film has been demonstrated. An integral part of many manufacturing processes for polymer products is the deliberate introduction of preferred molecular orientation by means of uniaxial ...
