Micro-mechanical modelling of the anisotropic behaviour of oriented semi-crystalline Polyethylene

Paper i proceeding, 2018

In this study, a so-called composite inclusion model is extended to predict the anisotropic behaviour of oriented Polyethylene tapes. An anisotropic model is developed for the amorphous phase. Two different sources of anisotropy are considered: an internal stress in the elastic network and an anisotropic viscoplastic flow rule.
