| Abstract: | In this paper, the subject of applying Moire Interferometry to measure residual stress around extruded hole is briefly discussed. This method is used for experimental study of stress flabbiness under circulating load. The interaction between residual stress and fatigue process of structure component is also discussed. Finally, several experimental results are presented. |
