Process Simulation of Hole Mandrelling in Steel Aircraft Parts

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