Remarks on Residual Stress Measurement by Hole-Drilling and Electronic Speckle Pattern Interferometry [PDF]
Hole drilling is the most widespread method for measuring residual stress. It is based on the principle that drilling a hole in the material causes a local stress relaxation; the initial residual stress can be calculated by measuring strain in ...

Residual stress measurement on the butt-welded area by electronic speckle pattern interferometry
Background: Residual stress always exists on any kind of welded area. This residual stress can cause the welded material to crack or fracture. For many years, the hole-drilling method has been widely used for measuring residual stress.
