Acoustic Emission Testing (AET)

Definition

Acoustic Emission Testing (AET) is a non-destructive testing method that detects elastic waves generated by active damage processes in materials.

Explanation

AET monitors structures in real time by capturing acoustic emission signals produced during crack growth, corrosion, or leakage.

Key Notes

• Passive NDT method
• Real-time monitoring
• Suitable for in-service inspection
