| Abstract: | In this paper , the residual stresses around cold worked holes were measured by application of Laser speckle interferometry in combination with radial cutting method. The experimental technique was investigated , and thderrors were discussed. The results showed that the experimental method used to measure the residual srress in small area was uncomplicated and accurate. |
