Vibration-based structural health monitoring.

Vibration-based Structural Health Monitoring (SHM) has grown in popularity due to various important practical and theoretical advantages, for instance: the wide availability of relatively inexpensive equipment, its ability to operate using naturally arising random vibration signals, its global nature, its high sensitivity to incipient damages even in complex structures, its simple automation for real time use. This special session aims at opening a forum where recent advances on vibration based SHM will be discussed with the focus being on smart mechanical and aerospace structures. In particular, novel SHM methodologies that may enable effective, robust, and accurate damage detection, identification (type/location) and quantification/characterization under normal operation uncertainty are welcome. Additionally, novel procedures for testing and validation of SHM methodologies with respect to damage type, size and employed sensor(s) location would be an added value.
