The forming process included 5 stages which two of them were about trimming and the remaining stages were about forming. A quarter model of the rim has been prepared with Altair Hypermesh and analyzed with LS-Dyna. Here are the three process that I have modeled.
The three forming phases can be seen at the following picture.

In this study, the rim has been considered with a variety of shapes and number of holes (between 12 to 18 holes) and a completely inverse cycle has been employed to evaluate the fatigue performance. Some results with regard to one step loading have been illustrated in the following pictures.
