Sonelastic® - Advanced Impulse Excitation TechniqueFor 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.

Sonelastic® HZElastic moduli characterization for accurate Finite Element Modeling and Analysis.
Knowing the elastic moduli exact values is crucial for accurate Finite Element Modeling and Analysis (FEM/FEA). Sonelastic® HZ enables measuring the Young’s modulus, shear modulus, Poisson´s ratio and damping of metallic alloys used in the manufacturing of ultrasonic horns and parts.
General specifications of the system:
- Young's modulus range: from 0.5 to 900 GPa.
- Frequency range: from 20 Hz to 96 kHz.
- Vibration modes: flexural, torsional and longitudinal.
- Dimension range: from 20 mm (3/4 inch) to 120 mm (4 3/4 inches).
- Geometries: Square or rectangular cross-section bars, cylinders, discs and rings.
Square cross-section bars
- Width and thickness (A): from 2 to 40 mm
- Length (L): from 20 to 120 mm.
- Aspect ratio: L/A ≥ 3.
Items of the Sonelastic® HZ:
- 01 Sonelastic® Software license with free 5-year updates.
- 01 Support for small samples SB-AP.
- 01 Set of manual impulse devices (01 light and 01 medium).
- 01 CA-DP, directional acoustic sensor.
- Installation and operation manuals in English.
Note: This System requires a computer with 196 kHz sound card not included.
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.
