Wrong Strain

Hi all,

I run an FEA analysis, viewed results of plastic strain, and we tested the part in real life. There are a lot of areas that have strain value exceed elongation value of the material . But in real life, the part doesn't break. What is the problem ? may problem be warpage on quad element used in raidus?

Thanks in advance.

Maybeyour simulation does not correctly present real behavior of the part?

Check BC, material, loading,... and meshing.

i think, there is problem about plastic strain. Because i can't view gissmo in Radioss and there are some warpage in quad element and i see more strain value than real test. may this be problem ?

And can i see gissmo in Radioss ?
