Seminar - Nanoindentation: Fundamental Mechanics and Practical Experience By Dr. Haimin Yao

Date: 10 March 2015 (Tuesday)

Time: 11:00 am – 12:00 pm

Venue: EF305, The Hong Kong Polytechnic University

Abstract:

This talk will include two parts. In the first part the development of innovative
methods for characterizing the mechanical properties of nanowires, nanobelts and
ultrathin films will be introduced. In the second part the fundamental understanding of
deformation mechanisms of a thin film multilayered structure under mechanical loading
and its removal characteristics involved in abrasive machining will be discussed.

Nanoindentation is a prevailing technology used to characterize the mechanical properties such as reduced modulus and hardness of solid materials with small dimensions or at small length scale. In this seminar, I will systematically introduce the fundamental contact mechanics behind the nanoindentation technology. Then, I will share some personal experience in using nanoindenation. Although this seminar mainly is for RS and RA in ME department, anyone who is interested in learning nanoindentation technology are welcome.

Bio-sketch:

Dr. Haimin Yao is an Assistant Professor in the Department of Mechanical Engineering at the Hong Kong Polytechnic University. He received his BEng and MEng degrees in Solid Mechanics from Tsinghua University in 2000 and 2002 respectively. After graduation, he went to Germany and studied at the Max-Planck Institute for Metals Research. In 2006, he obtained his Doctor degree in Chemistry from Universität Stuttgart. Then he moved to USA and worked at Brown University and Massachusetts Institute of Technology as a postdoctoral Research Associate. Dr. Yao joined ME department of the Hong Kong Polytechnic University in 2011.
