Abstract
A model of the blowing process for polyethylene terephthalate stretch blowmolded bottles is presented. This model uses a rubber constitutive relation. The free blown diameter and the stretch balance are derived from stress equilibrium. Free blow experiments show good agreement with the predictions.Keywords
