TITLE: TO INFINITY AND BEYOND - THE AMAZING USES OF INFINITE STRUCTURE THEORY

ABSTRACT:  What if there were simple formulae you could use to calibrate structural mobility measurements on beams, plates, pipes, large pressure vessels, aircraft fuselages, and other structures?  What if those same formulae could be used to estimate the mobilities of structures that haven't been built?  How about using them to estimate how mobility might change if you modify the material properties of an existing structure?  Great news - these formulae exist, are simple enough to code in a spreadsheet in minutes, and are perhaps the most invaluable tools a structural-acoustician has.  They simulate propagating waves in infinite structures, including beams, plates, and curved shells.  In this lecture I will explain these formulae and prove their worth with several practical examples. 

BIOGRAPHY:  Along with directing the Penn State CAV, Dr. Stephen A. Hambric is a Research Professor at the Applied Research Lab and a Professor in the Graduate Program in Acoustics. Prior to joining Penn State in 1996, Dr. Hambric worked for nine years in the Computational Mechanics Office at the Naval Surface Warfare Center, Carderock Division.  Dr. Hambric has directed many numerical and experimental flow, structural acoustics, and noise/vibration control research and development programs for the Navy, NASA, Army, U.S. industry, and the U.S. Nuclear Regulatory Commission.  He has authored or co-authored three books, over 80 conference papers, 40 journal articles, and two patents.  He teaches courses in Structural Acoustics, and Research and Writing for Acousticians on campus at Penn State, and also to off-campus students working in industry and government. He is a Fellow of the Institute for Noise Control Engineering (INCE) and of the American Society of Mechanical Engine!
ers (ASME), and former chair of the ASME Noise Control and Acoustics Division.  He was also the General Chair of the International Noise Control Engineering conference (Internoise) in 2012, held in New York City, and now serves on the Board of Directors of International INCE as Vice President for Rules and Governance.
