Modeling of Deformation Textures Evolution in Semi-Crystalline Polymers

Abstract

A composite model for plastic deformations of semi-crystalline polymersis used to simulate deformation textures evolution in these two-phase materials.Three types of textures are simulated: crystallographic texture,morphological texture, and molecular alignment within the amorphous domains.Predictions of these textures in deformed high density polyethylene(HDPE) are shown for a uniaxial tension test.
