Abstract

A new approach has been developed for modeling hot-drawing of semi-crystalline polypropylene (PP) under conditions similar to industrial thermoforming. The proposed model encompassed components derived from a combination of concepts including Buckley et. al., DSGZ, G'Sell-Jonas, theory of linear elasticity and multidimensional stresses based on a biaxiality ratio. The resulting constitutive model precisely describes the yield, strain softening followed by flow and hardening observed in hot-drawing of polypropylene.
