How to find out the elongation with FEA?
How to find out the elongation with FEA?
(OP)
Hello guys,
I'm permforming a FEA in a cast iron part. On the material specsheet has the information "elongation at fracture 15%" how can I find out this value in % on the part with FEA?
Thanks in advance!

The stress is below to the Ultimate Tensile Strength, but above to the Yield Tensile Strength.
@GregLocock
Yes, non-linear region. I'm performing linear FEA and convert to non-linear stress by Neuber calculation.
I know that this part doesn't broke on field and have infinite life, but when I perform FEA I reach values above to the Yield Stress. I asked to the responsable engineer for this part, and he reached values greater than mine. I believe that if FEA doesn't reach "elongation at fracture 15%" it won't broke, due to be cast iron (GJS-400-15).
