Design of Heterogeneous Heat Conducting and Elastic Structures with Imperfect Interface
Abstract
The results obtained in this project predict novel physical phenomena for multiphase systems that are imperfectly bonded or have bonds with better transport properties than any of the constituent materials. These results are unlike phenomena seen in more traditional treatments where the interface between constituents is treated as a "perfect bond". The difference is that sample and particle size effects are predicted, where as "perfect bond" models are incapable of capturing this physically observed phenomena. In addition to capturing the "size effect, the new mathematical methods developed in this project provide a systematic way for predicting new "size effects". These results have direct application to rigorous design rules for particle and fiber reinforced composite structures. The structures and reinforcements that can be treated using this new mathematical approach range from the very small scale (nanometers) to the very large scale (kilometers).
