摘要：

Stress measurements were made, using the X-ray diffraction technique, around a cold-expanded fastener hole in a 7050 T76 aluminium alloy plate. It was seen that cold expansion introduces large compressive residual stresses around the hole. The results show the difference between the residual stresses on the inlet and outlet faces, and the asymmetry of the residual stress field around the hole was observed on both faces.
