# Structural Health Monitoring: Latest Applications and Data Analysis
###### Abstract
The resultsreveal higher decibel drops in amplitude for connections made with additive technology compared to conventional methods, providing valuable insights for testing adhesive joints in additive manufacturing parts. The joints examination was also a subject of article [9], where inseparable joints in machine and vehicle construction were investigated, particularly focusing on hybrid joints combining adhesive bonding and sheet metal clinching. The results showed that sheet metal clinching significantly increased the joint strength, with shear strengths of 965 N for clinching and 476 N for adhesive bonding. The hybrid joints exhibited even higher strengths, with average forces of 1085 N for fully cured joints and 1486 N for joints made immediately after adhesive application, indicating the improved strength of the hybrid joint due to stabilization and better crosslinking conditions. Modern materials, creating the possibility of changing properties as a result of the influence of external factors and reconfiguration of their structure, became the subject of another work published in the Special Issue. Paper [10] explores the evaluation of thin dielectric layers in the THz frequency range using a tunable split-ring resonator-based metasurface. By changing the geometry of the metasurface's unit cells, the resonant frequency can be varied, allowing for the assessment of a nearby thin dielectric layer. The study utilizes finite element method simulations and establishes relationships between resonant frequencies and dielectric parameters, providing more comprehensive information for the evaluation of the material's permittivity compared to non-tunable metasurfaces. In conclusion, topics presented in the Special Issue titled \"Structural Health Monitoring: Latest Applications and Data Analysis\" cover a wide range of areas not only related to hardware solutions, including the implementation of sensing layers and new solutions in material technology, but also, to a large extent, to the use of advanced data science algorithms. The works cover a variety of applications, including nondestructive assessment of historic brick walls, monitoring of dam safety, evaluation of electrical sheets using magnetic Barkhausen noise, corrosion detection in aircraft structures, ultrasonic testing of additively manufactured components, monitoring of hybrid joints in mechanical engineering, study of tunable split-ring resonator-based metasurfaces for thin-film dielectric structures assessment, detecting real corrosion cracks, determining the strength of tendons in bridges, and assessing the thickness of concrete cover using microwave thermography. The papers present new and novel methodologies, advanced and complex data processing techniques, and original measurement approaches to increase the accuracy and reliability of structural health monitoring and material evaluation. These works confirm the upcoming trends in the development of SHM technologies, aimed at the development of the hardware layer by introducing new materials and methods of acquisition, but above all, advanced analysis of data. Bearing in mind the existing needs of the industry and the need for multi-threaded system operation and online analysis of the examined objects state, continuous and increasing progress in the SHM area should be expected in the coming years.
