Sonelastic® - Advanced Impulse Excitation Technique

For non-destructive elastic moduli and damping characterization of materials.

Sonelastic^® are systems based on the Impulse Excitation Technique (ASTM-E1876) for the accurate and non-destructive characterization of elastic moduli (E, G and Poisson ratio) and damping of materials. It is suitable to be used with a wide range of geometries and dimensions, and for room and high temperature characterizations.

Elastic properties of alloys used in ultrasonic horns

Table-1 shows the typical elastic properties of alloys used in the manufacturing of ultrasonic horns and sonotrodes. This information is for reference only; elastic properties vary significantly depending on:
- Lot and supplier;
- Heat treatment (please, see Table 2 for examples);
- Geometry and dimensions (please, see Table 3 for examples);
- Position along the billet/plate;
- Grain/cut direction (parallel / along with or perpendicular to the lamination).
For exact values, we recommend the material characterization performed by the Sonelastic^® HZ.
