“…Experimentally a decrease of both velocity and stiffness with an increase in transverse crack density was observed [21]. It was found that the reflection of the S0 mode from an artificial delamination is strongly dependent on the position of the delamination through the thickness of the laminate [22].…”

“…It is surprising to note that all predicted positions are beyond the right end of the delamination. It has been demonstrated that a higher propagation speed of S0 mode in the delaminated 0°layer can make the predicted delamination positions behind the actual delamination [16,17]. From the FEM simulations, the estimated speed of S0 mode in the 0°delaminated layer was 8483 m/s.…”

“…These studies reported that S0 and A0 guided Lamb mode can be used for damage (delamination) detection in composite laminates [1][2][3][4][5][6]. Quantitatively, delamination can be detected in cross ply composite laminates using guided Lamb wave [7]. It is important to analyze the scattered energy in arbitrary directions for characterizing the delaminations.…”

Multi-site delamination detection and quantification in composites through guided wave based global-local sensing AIP Conference Proceedings 1806, 020007 (2017) Abstract. This paper addresses a gap in the literature on the 3-dimensional scattering of the fundamental symmetric Lamb mode S0 from delimitations in composite plates. We study the scattering of low-frequency S0 Lamb mode from a delamination in a stiffened 4-ply CFRP composite plate with [0/0]S ply orientation. Far field scattering coefficients for the S0 Lamb mode are plotted as a function of circumferential position around the delamination using 3D FE simulations. Results show that the delamination size has less influence on S0 Lamb wave scattering in the low-frequency regime where the S0 mode is non-dispersive. Further analysis was done using two-dimensional FE simulation for different ply-layup orientations with S0 Lamb mode. This study shows that ply-layup orientation and through-thickness delamination location in fiber composite laminate have a significant influence on S0 Lamb mode interaction. We also analyzed the interaction of A0 Lamb mode for a few cases. This work will be useful for practical Lamb wave based inspection of composite plate structures.
