Contrôle-santé structurel passif à ondes guidées, basé sur des réseaux de capteurs ultrasonores désynchronisés, Passive guided wave structural health monitoring based on desynchronized ultrasonic sensor networks

Omar Bouchakour

L'évolution de la surveillance de l'état des structures (SHM) au cours des dernières années a vu émerger des réseaux de capteurs indépendants à faibles ressources matérielles. Cependant, les signaux enregistrés par ces capteurs pour faire de l'imagerie passive peuvent présenter des…, The evolution of structural health monitoring (SHM) in recent years has witnessed the emergence of independent sensor networks with limited material resources. However, the signals recorded by these sensors for passive imaging can exhibit desynchronizations that make it difficult to locate damage…
