Standard Condition Monitoring and Structural Health Monitoring schemes have been shown to operate robustly on the level of detection, with several successful implementations, where damage to a system is picked up by the change induced in its dynamic properties. However, the more advanced levels in the SHM hierarchy, such as localization and quantification of damage are often hard to achieve on the basis of conventional SHM tools. In response to this, Guided Wave (GW) methods prove successful in such higher levels of assessment, with potential to be used both periodically (for Non-Destructive Evaluation), as well as continuously, in the context of SHM. Applications cover a broad array of systems from civil, to mechanical and aerospace structures.

The session invites submissions relating to guided wave propagations in both isotropic and anisotropic media. Relevant topics include elastic wave propagation, linear and nonlinear phenomena, 1D/2D/3D propagation, time or frequency domain analysis methods and tools, simulation-based approaches for analyzing the underlying wave propagation phenomenon, as well inverse methods for GW-based detection and localization of flaws. The proposed schemes may be presented in the context of both local and global SHM technologies. Contributions dealing with validation of computational, diagnostic and prognostic schemes via experimental data are particularly welcomed.

The MS is organized under the auspices of the SNSF-Alphorn project: Fusion of Models and Data for Enriched Evaluation of Structural Health.
