Remarks on residual stress measurement by hole-drilling and electronic speckle pattern interferometry. [PDF]
ScientificWorldJournal, 2014 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 ...
