  • Laser interferometric measurements of air-coupled lamb waves 

    García Rodríguez, Mercedes; Yañez, Y.; García Hernández, Miguel J.; Salazar Soler, Jorge; Turó Peroy, Antonio; Chávez Domínguez, Juan Antonio (American Institute of Physics (AIP), 2010)
    Conference report
    Restricted access - author's decision
    In this paper, experimental measurements of the vibration pattern that results when an air-coupled A0 Lamb wave mode propagates in a plate are presented. Lamb waves are generated using an air-coupled piezoelectric transducer ...
  • High voltage pulser for NDE air-coupled lamb wave ultrasonic system
