    Professor Yueguang Wei elected as academician of the Chinese Academy of Sciences

  • On November 28, 2017, the Chinese Academy of Sciences announced the list of newly elected academicians in 2017. Through this election, 61 academicians of the Chinese Academy of Sciences and 16 foreign academicians of the Chinese Academy of Sciences were added. Professor Yueiguang Wei in the Department of Mechanics and Engineering Sciences of the College of Engineering at Peking University was elected into the Chinese Academy of Sciences.

    Prof. Wei joined the College of Engineering in November 2016. Previously he worked as a research fellow at the Institute of Mechanics, Chinese Academy of Sciences. He was formerly a visiting professor at University of California at Santa Barbara, University of California at Riverside, and Harvard University.

    For more than 20 years, Dr. Yueguang Wei developed the trans-scale mechanics theory and trans-scale mechanics method, and he applied the theory and methods to the characterizations of strength, toughness and failure of the advanced materials. The developed trans-scale theory and methods include: the trans-scale mechanics theory considering both strain gradient effects and surface/interface effects ("top down" theory); Finite element method which is suitable for strain gradient theory; Characterizations of mechanical properties from both atomic calculations and experimental observations and measurements of micro-structure evolutions ("bottom up" approach); Development of linkage law from "bottom up" to "top down" theory, and so on.

    In recent years, Dr. Yueguang Wei systematically used the above theory and method to describe the thin film delamination, the failures of thermal barrier coating system, the property characterizations of nanostructured materials, the failure of cementation system, as well as micro-scale friction and other issues.
