Lamb wave-based monitoring of shear failure of an adhesive lap joint

Abstract: The paper presents a study on the elastic wave propagation in adhesive joints of steel plates subjected to tensile loading. A single lap joint was chosen for analysis because of its simplicity and plurality of applications. Experimental investigations consisted of the uniaxial extension of prepared specimens. Force and displacement values were recorded by a testing machine. Simultaneously, guided Lamb waves were excited and signals of their propagation were collected in a number of points by piezoelectric tran… Show more

“…The continuous wavelet transform has been widely applied in the context of SHM for signal denoising 92 and feature extraction 93 . Specifically for adhesive joints, the continuous wavelet transform was used by Rucka et al 80 and Hong et al, 94 just to cite a few.…”

“…Methods for studying the state of a material are effective, in which measurements of the velocity of SAW are used [6,7,11,16,19,23]. The velocity of SAW depends on the elastic characteristics of the material and its density and is sensitive to the occurrence of plastic deformation [18], as well as mechanical stresses [2,13,14] in the material.…”
