Characterization of mode selective actuator and sensor systems for Lamb wave excitation
Abstract
Structural Health Monitoring (SHM) based on Lamb waves, a type of ultrasonic guided waves, is a promising techniquefor in-service inspection of composite structures. This study presents the development of mode selective actuator andsensor systems based on interdigital transducer (IDT) design. Various parameters such as wavelengths, number andapodization of electrodes as well as eigenfrequencies of the transducer are characterized. Therefore, an analytical modelbased on the theory of surface acoustic wave (SAW) filters is investigated in order to evaluate the acoustic response ofthe transducer. Furthermore, experimental tests on composite plates are performed.
