Hi, I am doing a static structural simulation with boundary conditions of displacement and force. I calculate the total stress but I am also interested to calculate the total force required for that displacement. I have a geometry with 3 layers, with some surfaces having bonded contact. 

In other words, I specifiy the displacement (of 3 micron in my case) on the top surface and a certain force on the bottom surface of the top layer. 

Now I want to calculate how much will be the force will be required to cause that displacement ( so how much force will be needed to lift that membrane to 3 micron)?? Is the reaction force the correct way to do this?

So using reaction force on the same face as the displacement? Or is there another way for this??

 

Please help!

Yes, force reaction would be useful in this situation. 
You can extract the force reaction at the boundary and then draw the chart between the force vs displacement, which will you to understand the variation of the force with the displacement. 
To create the chart you can follow the following forum thread
