This work aims to develop a continuum, multi-scale, physically-based model of the forming process for layered-silicate nanocomposites based on poly (ethylene terephthalate)(PET) matrices, as might be used for packaging. This challenge is tackled using:(1) a physically-based model of PET implemented into the FEM-based code ABAQUS,(2) RVEs with prescribed morphologies reflecting TEM images, and (3) nonlinear computational homogenisation. As a result, 2-D two-scale FEM-based simulations under biaxial deformations (constant width) enabled the extraction of macroscopic stress-strain curves at different silicate contents and processing temperatures. In particular, interesting features in terms of morphology changes and its impact on the macroscopic stress response were captured:(a) morphology change by particle re-orientation and pronounced bending,(b) macroscopic strain hardening due to platelet re-orientation and local strain stiffening,(c) facilitated platelet alignment, and platelet delamination in tactoids through sheardominated deformations and increasing temperature.
