| Abstract | The formation of pre-stressing layer with certain depth on the surface via hammering can effectively prolong the fatigue life of parts. It is necessary but difficult to accurately analyze the symmetry and synchronism of plastic deformation zone formed by hammering. In this work, we, herein, create an experimental method that tights the Q235 steel rods together via external force and study the plastic deformation zone near tight seam. Through morphology analysis, it is found that the cross profile of plastic deformation zone near tight seam is circular and radially symmetrical, indicating that the sharp of internal plastic deformation zone is spherical. Additionally, the result of dynamic strain experiment confirms that the result obtained by hammering the tight seam is reliable. © 2020 The Author(s) |
