Kurzfassung
Structural Health Monitoring (SHM) based on Lamb waves, a type of ultrasonic guided waves, is a promising method for in-service inspection of composite structures. In this study mode selective actuators are developed to excite a particular Lamb wave mode in composite plates. Different ma-nufacturing technologies based on monolithic piezoceramics with applied interdigitated electrodes and piezocomposites are described. A mode selective actuator is designed and optimized. Finite element modeling and experimental tests on quasi-isotropic composite plates are performed in order to characterize the mode selectivity of the actuators.
