Lecturer: Prof. Wang Yize is a Professor at School of Mechanical Engineering of Tianjin University. He obtained his PhD in Mechanics from Harbin Institute of Technology in 2009. After graduation, he performed his research as the JSPS Fellow in Tokyo Institute of Technology in Japan (2009.11-2011-11) and Humboldt Fellow in TU Freiberg in Germany (2013.06-2014.05). His research is mainly focused on the theory and application of elastic waves in solid mechanics. He has co-authored over 50 peer-reviewed scientific papers in which 50 papers are denoted as the first/corresponding author. His total citation is more than 1000 and the h-index is 23.

About the Lecture: Phononic crystals and mechanical metamaterials are arranged by different materials periodically, which can perform as the artificial structures. One of the prominent characteristics is the diverse energy bands in the elastic wave dispersion. As a result, the stop bands or band gaps will be generated, in which the elastic wave cannot propagate and the unusual wave behaviors will show. The appearances of phononic crystals and mechanical materials can enhance the technologies to control elastic waves. Their applications on some engineering fields would be achieved, e.g. new waveguides and filters, cloaking structures and reduction of the vibration and noise. This presentation will introduce some wave properties of mechanical metamaterials, describe the fundamental mechanisms and discuss the development in this field.
