Hello all,
I'm trying to calculate a ring deformation. In this calculation, I get the specific deformation of the ring. As you can see from , I want to give a circumferential pressure using the hoop to make it smaller and then the gap can be closed. I want to know how much force or pressure I need to use to get the deformation so I need to have a try. Then several questions come to me.
1.How to constrain? If I don't give the constraint, the ring will move to infinity. I don't know which way is best for this situation. Also the hoop should be considered in the constraint.
2.How to give the load? As the hoop is more narrow than the ring width in z direction, it contacts the ring at the middle with 25mm width. I use pressure applied in the contact surface. As the gap exists, the deformation will be non-uniform under stress. But the pressure is always uniform, is pressure suitable for the fact?
For your convenience, I attach the example here.
Thank you very much!
