T1 - To infinity and beyond - The amazing uses of infinite structure mobility theory
AU - Hambric, Stephen
N1 - Funding Information:
A reminder that I developed none of the infinite structure mobility formulae in this paper - all credit goes to Drs. Cremer, Heckl, Ungar, [6] and Skudrzyk [7]. Also, all of the measured mobilities and most of the plots were made by dedicated graduate students over the years, including Ben Doty (large shell [9] and elbowed pipe [10]), Andrew Munro (ribbed panels [11]), Micah Shepherd (sandwich panel [4]), and John Cunsolo (compressor [12]). Finally, I will always be indebted to Dr. Yun-Fan Hwang for first introducing me to infinite structure theory many years ago.

N2 - 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 have not yet 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 structuralacoustician has. They simulate propagating waves in infinite structures, including beams, plates, and curved shells. In this plenary lecture I will explain these formulae and prove their worth with several practical examples.
