Scales, Offset, and Axis Assignments

Hi everyone,
I am performing a tensile test on a test coupon bar, accordingly to the tutorial proposed at the part 3.1.5 of Nonlinear_FEA free ebook by Altair. I have some problems in plotting the stress-strain curve: I do not understand why some scale factors are introduced and why the designer chose those values. My main problem is which scale factors values choose for my plot: I use another .fem virtual desk, I create the spring and the RBE2, then I follow document/video steps.
Best regards
Martina

Hi
The scale factor is applied to have the unit consistency , since here the test data is compared with the analysis result and these two curves are plotted in the single page

Ok, thank you.
So, why the X component of tests results is multiplied by two? Is it due to simplifications during test procedure, or due to FE problem setting, or something else?

Hi
Its just scale factor applied for magnification.
