Stress Relief using Sub-Harmonic Vibration

[MatlsCorr]

Is anyone familiar with this technique?

Thank You

Not for pressure vessel or boiler code applications.

Not for use on aerospace parts... not enough value-added.

Vibratory peening is effective and useful in certain circumstances. See...

I've seen a 'peening gun' (basically a needle scaler with blunt needles), used to remove welding distortion in complex steel weldments.

It's skill-intensive but effective.

I wouldn't call it stress relief, because it doesn't relax locked-in stresses, it just offsets them with new local compressive stresses.
