Obtaining Ultimate Load Using “Riks” Method

QUESTION
I am using the Riks method in order to obtain the bending moment resistance of a beam. My material is aluminium, modeled as a continuous stress-strain curve (elastic and plastic properties). If i set a load value which is large enough, do i get a proportionality factor after the analysis, which i can use to multiply the load and to obtain the ultimate bending moment? If not, how can i, otherwise, go about this?

While running (and afterwards of course), you can open the .odb and check “LPF” in history output.
