Speaker: Prof. Lawrence A. Bergman, Professor Emeritus, Department of Aerospace Engineering, University of Illinois at Urbana Champaign

Talk Title: Targeted Energy Transfer: Intentional Use of Strong Nonlinearity for Vibration and Shock Control

Abstract: For more than fifteen years, our research group has been developing and applying the concept of Targeted Energy Transfer (TET) as an effective strategy for passively managing energy flows in dynamical systems subject to broadband transient loading. The technology has been studied analytically, computationally, and experimentally in applications covering a range of scales from nano to macro. I will briefly explain the principles behind TET, followed by a discussion of several of these applications demonstrating the efficacy of the technology.




Biography: Professor Lawrence A. Bergman received the B.S. in Mechanical Engineering from the Stevens Institute of Technology, and the M.S. in Civil Engineering and Ph.D. in Applied Mechanics from Case Western Reserve University. Prior to graduate school, he was on the technical staff of TRW, Inc. and the Lord Corporation. His research has been primarily in the areas of structural dynamics and control, nonlinear dynamics, applied stochastic processes, system identification, and computational methods. He was editor-in-chief of the ASME Journal of Vibration and Acoustics from 2000 through 2004, and served on the Executive Committee of the Applied Mechanics Division of ASME from 2009 -“ 2014, the last year as Chair. Professor Bergman has been a faculty member at the University of Illinois at Urbana-Champaign since 1979, where he is a professor in the Department of Aerospace Engineering, an affiliate professor of the Departments of Civil and Environmental Engineering and of Mechanical Science and Engineering, and where he served as assistant dean of the College of Engineering during the 1996-97 academic year. He is a Fellow of the American Society of Mechanical Engineers and an Associate Fellow of the American Institute of Aeronautics and Astronautics.
