| Résumé : |
An ultrasonic apparatus for measuring the elastic moduli of materials was designed .
The difficulty in measuring shear-wave velocity using ultrasund was overcome by a transducer cell (patent application).
Thus, both compressional and shear wave velocities can be measured in a relatively simple manner.
All the modules of the ultrasonic apparatus are of original design, and no off-the-shelf equipment was used.
The modules include: transducer holders, amplifiers, a frequency synthesizer and a computer interface.
The instrument represents a significant advance in the method of ultrasonic material testing and appears to have great market potential. |
