Abstract

As to optimize the ultrasonic transducer parameters and to interpret the measured results, knowledge about the sound field is required. That is relevant both in the fields of non-destructive testing (NDT) and of ultrasonic diagnostics in medicine. In many cases, the sound wave transmitted by the transducer passes layers of different impedances until it reaches the object to be tested and examined, resp. As the active element of the transducer has a finite aperture, which mainly is located not parallel to the surface of the specimen, and as the occuring interfaces are partly curved, the calculation of the sound field for such three-dimensional elastodynamic problems is not possible in the form of a closed solution.
