This book offers a collection of contributions from these research centers that represent the present state-of-the-art in the study of acoustic elastic interaction, being on the cutting edge of these investigations. This includes the description of acoustic scattering from submerged elastic objects and shells by the Resonance Scattering Theory of Flax, 410 0$aSeries on Stability, Vibration and Control of Systems, Series B 606 $aUnderwater acoustics 606 $aElastic analysis (Engineering) 615 0$aUnderwater acoustics. 615 0$aElastic analysis (Engineering) 676 $a534.2 676 $a620.2/5 676 $a620.25 701 $aGuran$b A$g(Ardeshir)$01083500 701 $aRipoche$b Jean$01823802 701 $aZiegler$b Franz$0747054 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911004830503321 996 $aAcoustic interactions with submerged elastic structures$94390758 997 $aUNINA
