Strange principal stress in postprocessing
Posted: Tue Apr 14, 2020 9:50 pm
Hello ! I have found a strange result in postprocessing, specifically the principal stress calculation.
Here's my result table :
and here is a cross check using two different online calculators :
The tensile principal stress from GiD is 4801.2 and from both online calculators is 3209.7.
In my model, the checked element has not actually cracked which means that the principal stress should be lower than 4400.0. With the GiD result it should be cracked, but I think that 3209.7 is actually right.
I can't figure out what is happening so I would really appreciate any help.
