Abstract

This study introduces a novel approach combining the time-reversal method with Lamb waves to evaluate the severity of debonding in composite glazed ceramic tile structures. Recognising that tile edges and corners are most susceptible to debonding, sensors were strategically placed in these locations as a standardised setting. The methodology centres on obtaining a reconstructed signal correlation coefficient that reflects the extent of structural damage. Sparse sensor based Reconstruction Algorithm for Probabilistic Inspection of Defects (RAPID) method is further deployed to image the probability distribution of damage in the investigated structures, where an innovative energy-based weighting factor is introduced for different sensing paths to enhance the detection resolution of the traditional RAPID method. Varied sizes of artificial debonding damage are successfully visualised in constructed images by the proposed method, offering a detailed and uniform approach to assess the extent of debonding across different specimens.

一种基于能量的增强成像方法，利用有限传感器数量的Lamb波时间反转来评估瓷砖面板的脱粘

本文提出了一种将时间反演法与兰姆波相结合的方法来评估复合釉面瓷砖结构的脱粘程度。认识到瓷砖的边缘和角落最容易脱落，传感器被战略性地放置在这些位置作为标准化设置。该方法的核心是获得反映结构损伤程度的重构信号相关系数。采用基于稀疏传感器的缺陷概率检测重构算法（RAPID）方法对所研究结构的损伤概率分布进行成像，并针对不同的感知路径引入基于能量的加权因子，提高了传统RAPID方法的检测分辨率。通过提出的方法，在构建的图像中成功地可视化了不同大小的人工脱粘损伤，提供了一种详细和统一的方法来评估不同标本的脱粘程度。
