ABSTRACT：
Piezoelectricity has a history of over 120 years. During the last few decades the main stream of piezoelectricity research has shifted from the applied physics and acoustics communities to the Ultrasonics, Ferroelectrics, and Frequency Control Society (UFFC-S) of the Institute of Electrical and Electronics Engineers (IEEE). The piezoelectricity research in UFFC-S has been steadily growing since after World War II. It presents many challenging mechanics problems from both materials and devices (structures). However, involvement from the mechanics community, which is very much needed, has been weak in general. This talk provides an overview of UFFC-S and its piezoelectricity research. Some mechanics problems are identified, to which mechanics researchers can make important contributions. It is hoped that the talk will help bridge the gap between the mechanics community and the UFFC-S on piezoelectricity research.
Brief Biography： Dr. Jiashi Yang received his B.E. and M.E. in engineering mechanics in 1982 and 1985 from Tsinghua University, and Ph.D. in civil engineering in 1994 from Princeton University. He was a Postdoctoral Fellow from 1993-94 at University of Missouri-Rolla, and from 1994-1995 at Rensselaer Polytechnic Institute. He was employed by Motorola, Inc. during 1995-97. Since 1997 he has been an Assistant and Associate Professor at the Department of Engineering Mechanics of University of Nebraska-Lincoln. Yang has published over 130 journal papers and three books: An Introduction to the theory of Piezoelectricity; The Mechanics of Piezoelectric Structures; Analysis of Piezoelectric Devices. During 2001-2005 he was the principal investigator of a research project on piezoelectric resonators funded by the US Army Research Office. He is an Associate Editor of the IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control. |
