Determination of Residual Stresses by Thermal Relaxation and Speckle Correlation Interferometry

Journal Article · · Strain
OSTI ID:780676
A new technique for the measurement of residual stresses is presented. The technique is based on strain measurements following thermal stress relaxation. The heat input is supplied by a low power infrared laser and the strain is measured with speckle pattern correlation interferometry. This paper presents a comprehensive overview of the technique and an example of how it has been applied in a practical situation.
