See Inside Materials Without Cutting Them Open
Every part tells a story when it vibrates. With a single tap, the Impulse Excitation Technique (IET) reveals a material’s stiffness, bonding quality, and hidden flaws – without damaging it.
Unlike destructive tests, this method works directly on finished parts, delivering real physics-based measurements instead of assumptions.
Why It Matters
Most failures aren’t visible on the surface. Cracks, weak bonds, and voids remain hidden – until it’s too late. Traditional destructive testing is costly, slow, and only valid for the single sample you break.
Impulse Excitation changes the game:
- Non-destructive – The part stays intact and usable.
- Precise – Detects property changes and microcracks early.
- Fast – Results in seconds, ideal for high-throughput QC.
- Scalable – Integrates into production lines and automated workflows.
How It Works
- A gentle tap excites the material.
- Resonance vibrations form inside the part.
- Frequencies and damping are measured and converted into elastic properties such as:
- Young’s modulus
- Shear modulus
- Poisson’s ratio
- Damping capacity
- Porosity indicators
Standards-based and repeatable, IET is described in ASTM E1876, C1259, C215, E3397 and more.
