Ecografía con ultrasonido (A-Scan)

Principle

An ultrasonic wave transmitted in a sample will be reflected at discontinuities (defects, cracks). From the relationship between the time of flight of the reflected wave and the sound velocity, the distance between ultrasonic transducer and defects (reflector) can be calculated. ...

Difracción del Tiempo de Vuelo (TOFD)

Principle

The depth of the cracks of an aluminiumtest block with seven cracks of different depths (saw cuts) is determined with two methods. During the experiment, the cracks in the material are examined with the aid of the ultrasound angle beam probe and the depth of the cracks is ...

Atenuación del ultrasonido en cuerpos sólidos

Principle

The damping of ultrasound in solid objects is determined for 2 (or optionally 3) different frequencies in the transmission mode. The resulting values are then compared to the corresponding literature values. In addition, the frequency dependence of the damping effect is analysed. ...

Ondas transversales en sólidos

Principle
The aim of this experiment is to study the generation and propagation of ultrasound waves in solid objects. In addition, the additional generation of transverse wave modes (shear wave modes) resulting from an oblique angle of incidence should be identified and the sound velocities ...

Características del campo de sonido

Principle
For the characterisation of round ultrasonic probes (piston-type transducers), the near-field length is an important quantity. It forms the zone of focus of an ultrasonic probe, in which the lateral resolving power has a maximum.
In this experiment, the sound pressure amplitudes of ...
