Modelling of Deformation Textures Evolution in Semi-Crystalline Polymers

Abstract

A composite model for plastic deformation of semi-crystalline polymers is 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.
