Abstract
Within the broad field of polymer and foam mechanics—at once highly intricate and deeply fascinating—this thesis seeks to advance the understanding of thermo-rheologically complex polymers and foams by developing mathematical models and approaches built upon extensive experimental investigations. An accurate, physically grounded and experimentally validated multiaxial constitutive description of semycrystalline polymers—which are thermo-rheologically complex—is developed within a continuum mechanical framework, in both the time and frequency domains and embedded with a novel parameter identification procedure. Multiscale analysis is performed on foams produced from those polymers, supporting them by experiments conducted under small and large deformations, in both quasi-static and dynamic conditions. Fundamental insights into the paradigmatic process-microstructure-mechanical property relationship are gained and successfully applied to the design and development of novel polymer foams and related technologies.
