Title : ( The Effect of Mandrel Speed upon the Residual Stress Distribution around Cold Expanded Hole )
Authors: Khalil Farhangdoost , Abbas Hosseini ,
Full TextAbstract
In this paper, cold hole expansion process on aluminum alloy 2A12TA was simulated using ABAQUS finite element package and the effect of different mandrel speeds upon residual stress distribution around cold expanded hole was considered. The results gained by simulation show major difference between the diagrams of residual stress distribution corresponding to different mandrel speeds. As mandrel speed increases the residual stress around cold expanded hole increases as well; hence, the fatigue life of fasten holes will be ascended.
