A three-phase micromechanical model for the elastic properties of semicrystalline polymers

Composite Inclusion Model Application The spherulitic structure of HDPE is presented by an aggregate of 2000 randomly generated inclusions (figure 4). Confrontation of the two-phase and three-phase model predictions with experimental data and the influence of the rigid-amorphous layer properties on the overall behavior can be seen in figures (5) and (6).
