Abstract

The multiscale modeling of polymer-based materials has many challenges that not yet been fully addressed in the literature. These challenges are summarized and discussed. A particular challenge is the modeling of the large distribution of microstates that exist in many bulk engineering polymer materials. A multiscale modeling approach is proposed to predict the bulk Young's modulus of polymers using a series of molecular models of individual polymer microstates and a statistics-based micromechanical modeling method. The method is applied to polyimide and polycarbonate material systems.
