SIMULATION: ULTRASOUNDS
The combination of the laser and ultrasound techniques means a wide range of applications in many fields of engineering. The ultrasound inspection methods are routinely used in non destructive tests for structures and engineering materials; the diagnosis through ultrasounds is constantly used in medicine, while the measurement of movements and dimensions by this technique is widely used in industry.
The simulation by finite elements makes it possible to study the two most important phenomena which concur in the method of ultrasounds by laser:
- Thermo-elastic generation
- Ablative generation
One of the many applications of this method is the determination of internal defects in materials without having to destroy the components. By way of illustration, we now present the results obtained in two aluminium test tubes, one of them with an internal notch.
