Structural Health Monitoring (SHM) is a process of implementing a damage identification procedure for mechanical, aerospace and civil engineering infrastructure. Any change in the geometric properties, boundary conditions and behavior of material is defined as damage of these systems. In the past 10 years, there has been an accelerated increase in the amount of research related to SHM . Hence, the increased interest in SHM to a wide range of industries and its correlated capability for significant life-safety and economic benefits has motivated the need for this thesis topic. The objective of this thesis study was to explore SHM approach to monitor and detect a change and/or damage in plates using Lamb wave propagation and surface response to excitation. First, the endurance of sensors and the adhesive used was evaluated. Next, the experimental data from the prepared samples was collected, compared, and evaluated. The obtained results indicated the severity and location of the defects.
