SHM system for anomaly detection of bolted joints in engineering structures

TL;DR: The elastic wave propagation phenomenon is applied as the basis for a system designed to detect anomalies in the pre-tensioned connections of engineering structures and can result in a Structural Health Monitoring (SHM) system that allows for the global assessment of structural integrity.

Investigations on the Impact of Material-Integrated Sensors with the Help of FEM-Based Modeling

TL;DR: By analyzing the inlay's impact on the material in terms of mechanical load, heat conduction, stress during integration and other impacts of integration, this wound effect is analyzed and the idea for the fabrication of future material-integrated sensors is presented.
Journal ArticleDOI

Amplitude modified sparse imaging for damage detection in quasi-isotropic composite laminates using non-contact laser induced Lamb waves.

TL;DR: The results show the efficiency of the proposed method with improved imaging performance and give comparisons for better parameter choice, as well as discussing by experimental investigation with different parameters.
Journal ArticleDOI

Damage detection with the fundamental mode of edge waves

TL;DR: In this article, Lamb or Rayleigh waves are used to detect mechanical damage using relatively simple geometries, yet real structures often incorporate features such as free or clamped edges, welds, rivets, etc.
