Abstract

In the field of acoustic arrays for high resolution sonar, transducers are driven with very high power densities and long pulse lengths. Due to mechanical losses in the materials, this produces a temperature rise which induces a variation of their characteristic properties. Such a phenomenon may lead to the mechanical breaking of the transducer.
