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.

Sonelastic® overview.

Sonelastic® HZ

Elastic 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.
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.
