How to measure force needed for defined deflection

I have a disc with a hole in the middle, a washer more or less.

I’m looking to find the force it will take to deflect the ID by a certain amount.

In this case the washer is 6ft OD 3ft ID and im deflecting the ID by 1in.

I’ve used a fixed value for the deflection but don’t see an easy way to measure the force required to achieve said deflection.

Any help would be nice.


What you need to use here is a Result control item - Area calculation - Sum of the Reaction force, assigned to the face(s) with imposed displacement. You can find more details here:
