Hello,
I am trying to find out the force required to crush a hem and how much an end bent down slightly (so it hits the bottom before hem is finished) would it affect the force needed. I am having trouble finding a way to solve for these in stress analysis because when I simulate this the part ends up passing through its self. Is there a way to stop this or a simple way of finding this force. Another problem is, I need to put in a higher number for the force then what should be necessary to get the same results. I've attached a picture of this uncompleted hem.
