Abstract:
Through millions of years evolution, many biomaterials and structures in nature have evolved extraordinary mechanical properties and performances. If we can extract underlying mechanics accounting for these excellences and then translate them into engineering counterparts, their properties and performance would be enhanced greatly. Motivated by this conception, I have been working in the field of Bio-inspired Mechanics and Materials (BiMM) for more than ten years. In this talk, I will share my experience and acquisitions in this journey by showing some representative works, including earlier studies on the adhesion system of gecko [1,2] and shell of a deep-sea snail [3], recent studies on the teeth of black carp fish [4-6] and microscopic screw dislocations in seashells [7] as well as an on-going study on the surface morphology of mangrove leaves [8]. State-of-the-art characterizations in combination with rigorous theoretical modeling, numerical simulations and experimental verifications not only forward our understanding of the fundamental mechanics responsible for these natural merits but also point out directions for biomimetic applications in engineering.
 

Biography of speaker:
Dr. Haimin Yao is an Associate Professor working 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 Stuttgart, and obtained his PhD degree in Chemistry from Universität Stuttgart in 2006. Afterwards, he moved to USA and worked as a Post-doctoral Research Associate at Brown University and MIT, respectively. In 2011, he joined the Hong Kong Polytechnic University. The research interests of Dr. Yao include Bio-inspired Mechanics and Materials, nanomechanics, contact mechanics, mechanical characterizations of biomaterials, mechanical behaviors of energy materials. So far, he has published more than 60 papers in refereed journals including PNAS, JMPS, Scientific Reports, Nanoscale, and Carbon and so on with total citations over 2000 (Google Scholar). Dr. Yao serves as editorial board members for Scientific Reports and Composites Communications.
