title = "Effect of thinckness on residual stress fields of cold expansion hole",
abstract = "In this paper, four axisymmetrical finite element models have been established to study effect of thinckness on residual stress fields of cold expansion hole, experiments were carried out to measure the residual stress of cold expansion hole and verify simulation results. The experiment results also show that cold expansion processing can decrease surface roughness of holes and improve surface quality. The FEM results show, at the top(bottom) surface, the volue of the radial residual stress varies with the plate's thickness, and the regularities of distribution of the radial residual stress are identical. The volue and the regularities of distribution of the circumferential residual stress vary with the plate's thickness. At the mid-thickness surface, the volue and the regularities of distribution of radial residual stress vary with the plate's thickness. The volue of the circumferential residual stress varies with the plate's thickness, and the regularities of distribution of the radial residual stress are identical.",
