Acoustic-Elastic Scattering Predictions and Experimental Verifications via Water Tank Experiments
2007
Lindwall, Dennis | Keiffer, Richard | Wood, Warren | Zingarelli, Robert
We are beginning a new series of laboratory acoustic experiments that will examine the detailed physics of acoustic-elastic scattering. These experiments will measure up-scattered acoustic waves, down-scattered elastic waves, and scattered interface waves from edges and embedded objects using a variety of is sensors. One of our goals is to verify a density-contrast hypothesis upon which the Wedge Assemblage numerical rough-interface scattering model is based and which is applicable to many sector acoustic environments. We are predicting some of these experimental results with calculations using fin finite difference (FD) codes that are designed for 2 and 3-D acoustic and 2-D elastic environments.
