Structural Health Monitoring (SHM) is a technique for detecting damage in structures using sensors and data analysis. It improves safety, reduces maintenance costs and extends the life of structures. SHM is used in bridges, buildings, aircraft and ships. Aerospace structures, including the airframe, wings and landing gear, must be lightweight yet strong to withstand various stresses. Materials like aluminium, titanium and composites are commonly used. SHM is crucial in aerospace for real-time monitoring and early detection of issues, enhancing safety and reducing downtime. Techniques include non-destructive testing, vibration analysis and fibre optic sensors. Future trends involve advanced materials, machine learning and smaller, more robust sensors for better monitoring. This book elucidates the concepts and innovative models around prospective developments with respect to structural health monitoring of aerospace structures. The topics covered in this extensive book deal with the core subjects of mechanical engineering. It will provide comprehensive knowledge to the readers.
