Acoustic Emission Test

Acoustic Emission Testing In Delhi


Acoustic emissions are stress waves produced by sudden movement in stressed materials. The common sources of acoustic emission are crack growth and plastic deformation. Unexpected movement at the source produces a stress wave that releases out into the test object and excites a sensitive piezoelectric sensor. As the stress in the material is elevated, emissions are generated. The signals from one or more sensors are amplified, measured for display and interpretation.
