Summary: The probability-based diagnostic imaging (PDI) algorithm is suitable for damage identification of complex composite structures, but its weight distribution function is relatively inaccurate, affecting damage localization accuracy. An improved PDI algorithm is proposed to correct this issue by adjusting the weight distribution function, resulting in improved accuracy in identifying damages on stiffened composite panels.

Summary: This paper reports on the application and challenges of a guided wave-based structural health monitoring methodology on a curved composite fuselage panel. An extensive network of piezoelectric transducers installed on the panel via diagnostic film and inkjet printed flexible circuits is used to detect barely visible impact damage. The threshold for damage detection is determined through statistical analysis and validated through an iterative cross-validation approach. The experimental results show that this method is effective in detecting and localizing BVID at different locations.

Summary: Structural health monitoring (SHM) is a multidisciplinary technique that uses guided waves (GWs) for damage detection. This paper combines the theoretical calculation method of elastic wave propagation with the orthogonal matching pursuit (OMP) algorithm to calculate the reflection-waves coefficient matrix (RCM) containing damage information. Additionally, a prediction approach based on recurrent neural networks (RNNs) is proposed to predict the damage reflection signal under different distances with 88.14% accuracy. The proposed approaches are effective for the localization of single and multiple damages, as demonstrated by experimental results.

Summary: Guided waves are becoming popular in the NDT industry due to their cost and time-saving potential in inspecting structures and high sensitivity in detecting micro-defects. This study uses experimental and numerical approaches to detect and locate cracks in isotropic plates using the second harmonic of the symmetric guided wave. The results show that the proposed technique is accurate, reliable, and does not require baseline data, providing an advantage over conventional ultrasonic testing techniques.

Summary: Damage diagnosis of thin-walled structures has been successfully performed through tomography and machine learning-driven methods, with good performance in processing Lamb waves. However, traditional approaches do not work well for composites due to their anisotropy and complex damage mechanisms. To overcome these limitations, this work proposes a CNN-based algorithm that localizes damage by processing Lamb waves without feature extraction, and it outperforms traditional methods.

Summary: Fiber Bragg grating (FBG) sensors are considered ideal for structural health monitoring (SHM) due to their small size, light weight, ability to be embedded, and ability to be multiplexed. Recently, there has been renewed interest in using FBG sensors for gravity wave (GW) measurements, with an edge filtering approach that greatly increases sensitivity. This study utilizes the phenomenon of acoustic signal transfer between fibers to develop an SHM system capable of damage localization using a single FBG sensor. The proposed approach has the potential to significantly reduce equipment costs and promote widespread acceptance of SHM systems in structures.

Summary: This paper proposes a damage position imaging and tracking technology for composite plate-like structures based on linear annular path damage probability distribution and ultrasonic guided wave. By analyzing the propagation velocity characteristics of guided waves on composite structures, the time-of-flight (TOF) map for all search points on each path is pre-constructed. The annular damage probability distribution map of each sensing path is obtained by combining the damage TOFs and absolute TOF difference threshold. The total damage probability of the whole monitoring region is obtained by summing up the path damage probability, which directly reflects the current damage position.
