Abstract

Residual stresses is measured using a new technique combining hole indentation with Electronic Speckle Pattern Interferometry (ESPI). The technique is superior to conventional methods such as the widely used rosette strain-gage hole drilling technique in the ease of experimental set up and the use of optics in strain measurement allows results to be displayed in real-time. The technique is fast, simple, less destructive and has great potential to be developed into a quality inspection tool in the production/field environment.
