How to Measure Young's Modulus Non-Destructively
Fast and fully non-destructive measurement based on natural resonance of your components.
The Method
GrindoSonic measures Young’s modulus using the Impulse Excitation Technique (IET). The test specimen is lightly excited by a mechanical impulse, causing it to vibrate at its natural resonance frequencies.
These frequencies are directly related to:
- Elastic stiffness of the material
- Geometry of the part
- Mass and density
By accurately measuring resonance frequencies and combining them with known dimensions and density, Young’s modulus is calculated according to ASTM E1876 and ISO 22259.
How It Works
Excite
Light mechanical impulse causes natural vibration
Measure
Capture resonance frequencies accurately
Calculate
Derive Young's modulus from frequency, mass, geometry
Key Benefits
Elastic Regime
Excitation is very small—material remains undamaged
Repeatable
Same sample can be tested multiple times
Seconds
Results in seconds, not minutes or hours
Full Component
Evaluates entire part, sensitive to internal defects
IET vs. Local Techniques
Unlike local techniques that measure only specific points, GrindoSonic IET evaluates the entire component. This makes it highly sensitive to:
- Microstructural changes
- Porosity throughout the volume
- Internal defects
Applications
GrindoSonic IET is ideal for:
- Rapid material characterization — R&D and new material development
- Quality control — incoming inspection, process monitoring
- 100% inspection — industrial production environments
