摘要: This paper demonstrates the effectiveness of certain structural health monitoring (SHM) strategies based on propagation guided elastic waves within thin-walled shell structures. is realized results numerical and experimental investigations obtained by use spectral finite element method (SFEM) together with laser scanning vibrometry (LSV) subsequent application two different integral-based indices for damage quantification, these being integral mean value (IMV) root square (RMS). Numerical tests SFEM were carried out a plate through-hole damage, cracked fuselage section stiffeners wing skin, all made aluminium. Experimental measurements LSV included aluminium plate, composite stabilizer PZL W-3A helicopter, simulated damage. During sensitivity both IMV RMS was tested considering various displacement components, signal timescales or weighting factors. A practical quick construction maps also presented.
