In this work, Lamb waves have been generated in a thin aluminum plate by bonding a piezoceramic actuator onto the plate. The acoustic pressure immediately above the plate was measured by a needle hydrophone, coupled to the plate through a thin oil la

The measurement of piezoelectric coefficient d33 is made using devices like the Berlincourt Meter ®, based on a force generator internally calibrated by a reference piezoelectric element which measures the charge ratio Culomb/Newton. For estructures

Non-Destructive Testing, as well as ultrasonic emission, frequently uses resonant transducers made with 1-3 piezocomposites. When the piezocomposite transducer is used for ultrasonic emission in air, it is necessary the use of high amplitude pulses t

Great efforts have been made over the last years to avoid the use of coupling agents between ultrasonic transducers and sample materials for NDE applications. Two different technologies compite for this particular application: piezoelectric and elect

Acomparative study between the nonlinear behavior of a composite and the piezoceramic, that has been used for it, has been carried out. This characterization is necessary to use the composite in power transducer applications. A study of the changes o
