Towards Cyber-Physical Security for Additively Manufactured Parts via In Situ Monitoring and Electromechanical Impedance
The layer-by-layer nature of additive manufacturing (AM) allows for toolless fabrication of highly complex geometries that cannot be made via traditional processes. AM is unique in its ability to precisely define both the material properties and geometric shape throughout the volume of a part, …

Structural Health Monitoring of Adhesively Bonded Joints With Piezoelectric Wafer Active Sensors
… focus of this research was directed towards the electromechanical impedance method for disbond detection. The electromechanical impedance (EMI) method was modeled extensively with analytical and finite element method; the theoretical predictions were compared with carefully conducted experiments …

A Comprehensive Integrity Monitoring System for Bolted Flange Connections
… The piezo-based active sensing method and the electromechanical impedance (EMI) method provide different approaches to monitor the characteristic variations in the metal-to-metal sealing condition. Upon seal failure, the acoustics generated by the sudden release of the escaping pressurized …

Impedance-based Nondestructive Evaluation for Additive Manufacturing
Impedance-based Non-Destructive Evaluation for Additive Manufacturing (INDEAM) is rooted in the field of Structural Health Monitoring (SHM). INDEAM generalizes the structure-to-itself comparisons characteristic of the SHM process through introduction of inter-part comparisons: instead of comparing …
