With the increasing advancements of nanotechnology, material properties of nano-structures are actively investigated. Especially, the size effects on mechanical and thermal properties, have attracted significant interest. From an engineering point of view, it is imperative not only to explain the material behavior but also to invent metamaterials with tunable properties according to the future needs. The key to design and fabricate complex metamaterials and nanomaterials is to understand their behavior and to have a computational framework highly capable of predicting the overall material response. In particular, size-dependence and heterogeneity play a significant role in achieving sophisticated material behavior, both requiring further developments from the computational mechanics perspective. The main objective of this project is to develop a novel, reliable and efficient computational framework to capture size effects via generalized interfaces with application to non-linear thermomechanical behavior at finite strains, in which theoretical foundations as well as numerical implementations are addressed. A fundamental challenge and one of the key features of the project is to fully resolve every topic within a non-linear framework at finite deformations.
