Abstract
It has recently been demonstrated theoretically and experimentally that Green's functions (impulse responses) can be estimated from coherent processing of random vibrations using only passive sensors studies in various applications (ultrasonics, acoustic, seismic ... ). This article investigates the passive-only estimation of coherent guided waves waves (DC - 500 kHz) in an aluminum plate, of thickness comparable to aircraft fuselage and wing panels. Furthermore these passively reconstructed waveforrns can also be used for damage detection in the plate similarly to conventional active testing. Based on this study, passive structural health monitoring techniques for aircraft panels can be developed using random vibrations.
