Seminar - Nonlinear and time-variant behaviour for structural damage detection - recent developments by Prof. Wieslaw J. Staszewski
日期：2018 年 11 月 26 日 ( 星期一)
Time：11:00 am - 12:00 pm
Structural damage detection methods based on nonlinear and time-variant phenomena have attracted many research investigations. Various methods based on ultrasonic wave propagation and vibration testing will be demonstrated. The major focus will be on recent developments and work performed at the AGH University of Science and Technology in Krakow, Poland. Examples of novel excitation schemes, enhancement techniques and signal processing framework used for the analysis of nonlinear vibro-acoustic field will be presented. Time-variant dynamics of engineering systems will be also demonstrated. Application examples will relate to crack detection in metallic components, impact damage detection in composites and detection of abrupt changes of stiffness in frame-like structures. Some potential future plans will be discussed.
Wieslaw J. Staszewski is a Professor of Mechanical Engineering in the Department of Robotics and Mechatronics at the AGH University of Science and Technology in Krakow, Poland. He received the B.Sc. and M.Sc. degrees in Mechanical Engineering from the Technical University of Poznań, Poland, in 1985 and 1986, respectively, and a Ph.D. in Mechanical Engineering from the Victoria University of Manchester, UK, in 1994. He worked for three years in the Technical University of Poznan, Poland. He then spent six years, including eighteen months British Council Fellowship at the Victoria University of Manchester, UK. In 1995 he joined the Department of Mechanical Engineering at the University of Sheffield, UK, where he was promoted to a Personal Chair in 2005. He joined the AGH University of Science and Technology in Krakow in September 2011.
Prof. Staszewski has experience of research collaborative projects both in the UK and Europe, working with industrial partners and the EC. He is the author of over 480 research publications, predominantly in the damage detection and advanced signal processing areas. This includes 21 book contributions and over 180 refereed journal papers. Prof. Staszewski is the Associate Editor of five international journals, including Smart Materials and Structures, Structural Health Monitoring and Structural Control and Health Monitoring. He has been involved in organisation of a number of international conferences and invited to present seminars, lectures, conference keynote addresses in the UK, Europe, USA and Asia. Prof. Staszewski a Chartered Engineer, a Fellow of the Institute of Physics. Prof. Staszewski was awarded a DSc by the Polish Academy of Sciences in October 2001 for his research contribution to Mechanical Engineering.
