Structural health monitoring (SHM) is a relatively new and alternative way of non-destructive inspection (NDI). It is the process of implementing a damage detection and characterization strategy for composite structures. The basis of SHM is the application of permanent fixed sensors on a structure, combined with minimum manual intervention to monitor its structural integrity. These sensors detect changes to the material and/or geometric properties of a structural system, including changes to the boundary conditions and system connectivity, which adversely affect the system''s performance.This book''s primary focus is on the diagnostics element of SHM, namely damage detection. The techniques covered include the use of fiber optic sensors for strain measurement, microelectromechanical systems and accelerometers for vibration measurement, active ultrasonics, passive acoustic emission monitoring, and electromechanical impedance measurements. Contributed chapters written by leading researchers in the field describe each of these techniques, making it a key text for researchers and NDI practitioners as well as postgraduate students in a number of specialties including materials, aerospace, mechanical and computational engineering.
