Abstract We review features of a recently-proposed, micromechanically-based constitutive model of large plastic deformation and texture evolution in initially isotropic semi-crystalline polymers, and critically compare model predictions with experimental results for high-density polyethylene (HDPE) under different modes of deformation. Attention is focused on macroscopic stress-strain response and the evolution of crystallographic, morphological, and macromolecular textures in HDPE subject to uniaxial compression and tension, simple shear and plane strain compression. Comparison of the predicted results with experimental observations (e.g., stress-strain behavior, and wide-angle x-ray scattering WAXS studies of deformed material) shows excellent agreement.
