“…Figure 12 shows the Hilbert envelope of the asymmetrical mode of guided wave signals received at various receiver positions. The envelope of the guided wave signal, represented by H(t), is obtained using the Hilbert transform and can be expressed using the following equation [45]: In the case of defect-free, both S 0 and A 0 modes are reflected from the leading and trailing edge of the plate. In the case of delamination, the A 0 mode is reverberated multiple times within the delamination due to the displacement profile of the A 0 mode being perpendicular to the delamination.…”

“…Naresh Kumar presented a guided wave inspection method to determine delamination by analyzing the local response from the composite material using a single transmitter and receiver [39]. Several factors that influence the guided wave propagation in composites are the multilayered structure, anisotropic properties, specimen boundaries, mode dispersion, distortion, multiple overlapped modes, and mode conversion [40][41][42][43][44][45].…”

Multi-layered composite materials are being used in various engineering fields, such as aerospace, automobile, and wind energy, because of their superior material properties. Due to various impact loads during the service life of composite structures, different types of defects can occur, such as matrix cracking, fiber breakage, delaminations, etc. In this research, a novel SHM technique for delamination detection and localization using a minimum number of sensors is proposed. The analytical, numerical, and experimental analysis of GW was performed to increase the probability of detection and localization of delaminations in CFRP material. A new analytical model was developed, which enables identifying converted and transmitted modes in the presence of multiple GW modes. A 2D FFT-based spatial filtering was used to filter the GW modes. The dominant A0 mode was separated to inspect the delamination. Phase velocity is one of the important features in GW inspection to localize the delamination. A phase spectrum approach was developed to reconstruct the phase velocity dispersion of the GW modes in case material properties are unknown.

Abstract. The present research focusses on the development of a robust data-driven damage diagnosis technique to detect different types of damages in a hybrid metal-composite (HMC) plate specimen resulting from manufacturing processes, loading conditions, and ambient environmental conditions. These defects over a course of time deteriorate the load-bearing capacity of the HMC’s and in turn, their reliability in terms of safe operation. In this work, ultrasonic guided waves (UGW) are used for non-destructive evaluation (NDE) of the HMC. The use of UGW for NDE offers advantages such as long-range inspection and sensitivity to small-sized surface and sub-surface damages. The ultrasonic tests are simulated using a pitch-catch active sensing technique at a typical frequency-mode pair best suited to detect and classify damages in the HMCs. The damage-sensitive feature is extracted from the received UGW using Hilbert transform-based feature extraction method. The damage indicator is classified in the damage-sensitive feature space using the root mean square technique identified as outliers, which is further used to classify the detected damages. The achieved results manifest the ability of the proposed technique to be a part of the industrial structural integrity inspection process typically for HMCs in detecting and classifying embedded damages with high accuracy.

“…It was also observed that A0 mode dispersion at delamination's in composites is more complex and intricate than in isotropic plates [14], and it is affected by the delamination size to wavelength ratio as well as the delamination damage location through the thickness of the plate. Papanaboina et al [22] investigated multi-layered carbon fibre reinforced panel (CFRP) composites and determined the depth of delamination by comparing the A0 mode's amplitude and estimating location by calculating TOF. Hervin et al [15] employed the A0 mode to explore GW scattering and propagation in a quasi-isotropic laminate with asymmetrically positioned delamination at various depths, and full-field noncontact laser measurements were used to observe wave entrapment and scattering in the delaminated zone.…”

Guided wave (GW) based structural health monitoring (SHM) techniques being developed by researchers frequently use amplitude and group velocity variations between healthy and damage-affected GW modes to detect and localize damage. Nonetheless, external variables such as temperature and moisture influence these features, which were not considered in previous studies, particularly in the presence of damage in honeycomb composite sandwich structures (HCSS). Therefore, a coordinated numerical and experimental study was carried out in an effort to examine the characteristics of GW propagation in an HCSS for two damages: a disbond between the face sheet and the core, and delamination between the face sheet layers for a temperature range of $0^o$ to $90^o$ C. Computationally efficient two-dimensional (2D) numerical models were developed using COMSOL Multiphysics that takes into account a variety of temperature-related phenomena, such as thermal stresses and changes in the material properties of honeycomb sandwich and piezoelectric wafer transducers (PZTs). The amplitude and group velocity of the fundamental anti-symmetric (A0) mode are found to increase in the presence of a disbond and decrease in the presence of face sheet delamination. However, it is observed that there is a linear decrease in the amplitude of A0 mode for both the healthy and damaged cases with an increase in temperature. Since the A0 mode is widely employed for interrogation due to its defect sensitivity, an amplitude and group velocity adjustment equation with temperature change is proposed. Finally, considering the amplitude difference of normalised A0 mode, the two damages are localized within a network of PZTs by using a probability-based signal difference coefficient (SDC) method, which is found to be efficient and reliable for SHM of HCSS under variable temperature conditions.
