    • ( Exchange Programme )
    • The properties of materials are the responses of materials to external fields, which can be a stress field, a temperature/thermal field, an electric field, a magnetic field, or any combination of them. The response of a material to a specific external field has its distinct characteristics, yet different responses correlate with each other, enabling various functional materials. This course covers the fundamental concepts that describe/determine the mechanical, thermal, electrical, magnetic, and optical properties of various materials. The roles of composition, bonding, and structure (crystalline, defects, and microstructure) in controlling and influencing the properties as well as the methods to measure/evaluate the various properties are discussed. The correlation between different properties will also be explored.

    • Prof. Kong received his Ph. D from Tsinghua Universiy in 2005, after that he worked as post-doctorate fellow at the University of Montreal, and then the University of Western Ontario. He joined Shanghai Jiao Tong University in 2009.

      His current research focuses on computational and theoretical investigations of the structure and mechanical properties of non-equilibrium materials, as well as the interfacial structure and interfacial behavior of solid-melt interfaces, by using molecular dynamics simulations and/or first principles calculations. These investigations facilitate the understanding of the underlying physics of these materials.
