Abstract

A micromechanically-based composite model is proposed to study plasticity and anisotropy evolution is Semi-Crystalline Polymers. Since we are considering large deformations, it appears reasonable to neglect elasticity in this model. A combination of the behaviors of the phases (crystalline, amorphous) is used to describe the behavior of the basic unit element (composite inclusion) that constitutes these materials. A modified Taylor-like interaction law is proposed to deal with the sigularity problems related to the lack of insufficient plasticity mechanisms in some inclusions. Applications of this models are made to predict the behavior and anisotropy evolution in deformed High Density Polyethlene. Comparisons of our predictions to experimental data are encouraging.
