Strain sensing of interior structural radiation modes on a simply supported panel

Ben S. Cazzolato, Colin H. Hansen (2005)

Electronic Journal Technical Acoustics, 25 , p1-13

Abstract:

Radiation modes have shown great promise as a suitable measure for estimating the power radiated from structures into both the free field and enclosures. These modes may be sensed with either discrete out-of-plane transducers or continuous strain transducers. Here appropriate sensor shape equations are derived to accurately quantify the interior radiation modes from a simply supported panel radiating into a cavity using piezo-electric strain transducers.
