The concept of damage detection using sensors in composite panels is of growing interest, due to the reduction in maintenance activity and increasing of the aircraft safety. Piezoelectric materials have been widely used to build a variety of transducers for activating and receiving Lamb waves which ...

Unlike the conventional MUSIC algorithm, the proposed model-based 2D MUSIC damage identification algorithm is deduced based on the assumption of near-field according to the propagation model of guided waves. Since scattered signals contain the location information of damage, the cross-correlation ...
Waveforms of propagating flexural waves can reveal plentiful information about local anomalies caused by damage, and the local anomalies can be used for damage identification. However, the local anomalies can be masked by the interference of measurement noise and global trends of the waveforms, and ...
Damage mechanism identification has scientific and practical ramifications for the structural health monitoring, design, and application of composite systems. Recent advances in machine learning uncover pathways to identify the waveform-damage mechanism

The issue of uncertainty in material properties in structural damage detection with fuzzy logic is addressed by [30–33], with use of the fuzzy cognitive maps [30] used to solve this problem. Recently Meitzler et al. [1] have proposed an ultrasonic crack detection system, which uses ...
Consequently, it will affect the judgment of impact damage. Time difference localization and intelligent algorithm are employed to identify the impact location [6–8]. The former is to calculate the position of impact point using at least three sensors to detect the arrival time of acoustic ...
Unfortunately, improperly assumed or derived through homogenisation elastic material properties can lead to larger wave velocity changes than caused by damage. In order to account for this problem, the elastic constants are estimated based on experimental measurements of Lamb waves and optimisation ...
