Abstract

Observations are reported on isotactic poly(propylene) (iPP) in a series of tensile loading-unloading tests with a constant strain rate at room temperature. A constitutive model is developed for the elastoplastic behavior of a semicrystalline polymer at isothermal uniaxial deformations with small strains. The stress-strain relations are determined by 5 adjustable parameters which are found by fitting the experimental data.
