Residual stress measurement on the butt-welded area by electronic speckle pattern interferometry
Nuclear Engineering and Technology, 2015 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.
