| Abstract: | This is to study a measuring method of residual stresses distribution around cold worked fastener holes. A radial cutting is introduced for relaxing circular residual stresses and the displacement produced therea fter is measured by moire interferometry. In order to obtain high contrast strain fringe pattern, the photocarrier-shearing technique is used. |

| Keywords: | residual stress moire interferometry photocarrier-shearing method cold work. |
