Hi everybody!
I'm trying to calculate the SF as SF=Allowable stress/Von Mises stress.
I define a Element Table for SEQV stress and and I label this table as SVM. I calculate SF as follows:
SALLOW,500e6
SFACT,1
SFCALC,SF,SVM,,1
Next, I plot SF element Table. However, minimal SF calculated doesn't correspond to maximal Von Mises Stress. Actually, If I plot Von Mises Element Table, it doesn´t correspond to Nodal VOn Mises Stress.
I don't understand what SF is calculating. And what is keeping at Element tables?
Best Regards,
