Multiphysics simulation of thermoplastic polymer crystallization

Abstract The main goal of the presented work is to implement a robust framework for the computation of the crystallization kinetics of semi-crystalline thermoplastics by using a multiscale approach. The purpose of multiscale modeling is to assess parameters influencing microstructure formation that would otherwise require very time-consuming analysis with experiments. The numerical method, crystallization kinetics and their implementation into numerical software operating at macro- and micro-scale are described as well as the experimental data needed to prepare and validate numerical results.
