Abstract

This work intends to lay the groundwork for an interlaboratory comparison of methodologies for Structural Health Monitoring, employing integrated transducers for the impact localization on structures. The study is conducted on an aluminum plate, on which impacts are produced by metal spheres of different mass, dropping from a fixed height, and the generated Lamb waves are detected by PZT sensors glued on the surface. A Laser Doppler Vibrometer is used for validation purposes, and different data processing and feature extraction algorithms are applied for comparison, with the goal of training Machine Learning models. The primary objective is to establish an optimized procedure that ensures reproducibility of results across different laboratories, for a possible in-field transfer.
