Need help finding an equivalent force for a given deflection

Hey all...quick question. I have a small composite clip for which I am doing a 2D Plane Stress analysis. I have cut the clip in half and have fixed it at one end. The other end is being forced to deflect 0.030". The analysis runs great, but now I would like to know how to calculate the 'equivalent force' that would be required to produce that given deflection. I tried creating a measure but didn't really know what to do with it once it was created. Any insight would be greatly appreciated.

 

The file clip_main is the whole clip. The file clip_main_sim is an inheritance model part that I am using for the Simulate analysis.

 

Thanks.

Mark, admittedly I did not open your file. That being said though, you should be able to add a contraint and instead of making it fixed, select the prescribed displacement button (to the right of the default fixed button). If you type in .030 you should then be able to create a force measure that measures the force at that constraint.

alternatively you could assign a easily scalled force load (1 unit) and then scale as needed to give you the desired displacement.

Thanks Chris...I failed to notice that you could assign the measurement directly under the category 'Reaction at constraint'. Much appreciated.
