Abstract

The processing technology of steel structural elements of aircraft parts is especially important since, if improperly processed, this material can be subjected to weathering, causing corrosion. Furthermore, special attention is paid to the walls of holes used for bolting. Since holes can become stress concentrators, the paper proposes to strengthen them by implementing the SPD (surface plastic deformation) method. The article describes the simulation of the mandrelling process, which is more efficient and less traumatic. Therefore, changes in the walls of holes as a result of deformation are shown, which occur after the process of hole mandrelling.
