Abstract
AbstractUltrasonic peening treatment is a modern technique that enhances the surface properties of the metallic components by imposing static and dynamic loadings. The efficiency of this technique dramatically is dependent on the controlling parameters of ultrasonic peening treatment. In this study, an experimental and numerical investigation on ultrasonic peening treatment was carried out. The numerically predicted residual stress profile was verified using x‐ray diffraction measurement. Moreover, a parametric study was performed to investigate the effect of needle diameter, impact number, device moving velocity and static force on residual stress distribution. Based on the results, increasing in needle diameter, impact number and static force had positive effects on residual stress profile. In contrast, higher device moving velocity caused to emerge undesirable effects.
