Scales, Offset, and Axis Assignments

Recommended Posts

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?
