Abstract

The yield strain variation in poly(ethylene terephthalate) (PET) as a function of strain rate, temperature and PET structure to reveal the similarity and difference with the yield stress behavior was analyzed. Oriented semicrytalline PET samples displayed a linear increase in yield strain e _y with logarithmic strain rate, similar to normalized yield stress σ_y. The strain rate dependence of e_y was smaller at higher temperature and for PET of increased crystallinity and orientation. A dimensional analysis revealed that PET had a distinct transition in both e _y and its strain rate dependence at the activation volume of ca. 1.1 nm³.
