About ultimate stress and displacement for nonlinear analysis

I am implementing a material nonlinear simulation for an aluminum tube. I fixed an end of the tube and used displacement constraint to another end.

The ultimate stress of the material is 440MPa. What simulation or how to set up parameter to measure the moving constraint when the ultimate stress reaches exactly 440Mpa?

It seems like I should do the calculations myself, No any method to set up a measurement point for the value, isn't it? 

Yes, 2-3 intermediate steps are enough.

@skunks Thanks for your kind answer!
In other words, is there any way to get a graph of the "Failure Index versus Displacement" in this case. I want to know how much displacement there is when the failure index is exactly 1.
