报告摘要：
In the past decades, structural health monitoring has been an active research area with aims to substantially increase structural integrity for various engineering structures with improved performance. Damage identification as a key aspect of structural health monitoring techniques is a typical inverse approach based on fusion of extracted signal features from sensor network. The seminar presents some recent results of damage identification using guided wave signals from active sensor network in beams, panels and tubes in terms of signal processing, extraction of signal features, and inverse algorithms for damage identification, such as triangulation, correlation, time-reversal, and artificial neural network based on a concept of digital damage figureprints. Some new results on monitoring delamination growth and impact damage in GF/EP laminates based on electrical resistivity tomography aided by conductive nanoparticles in the laminates are also discussed.
