Dear all!

I have simulated a compression test using cyclic symmetry in the structure in Abaqus. After finding the results I want to plot stress-strain graph by calculating the stress from the reaction force values. I want to know while dividing the reaction force by the area, which cross-sectional area do I need to consider? Is it the cross-sectional area of the whole cylindrical structure or the cyclic symmetric part only?

Thanks a lot in advance!!
