Minimum material properties? structural steel Linear, NL analysis
(OP)
Hi
What are the minimum required material properties to perform static structural steel linear and non-linear analysis?
I have used the data available in Ansys WB library for structural steel and just made some modifications on yielding strengths. I'm getting reasonable results when using NL material for Von-Mises stress, however, the results are non-realistic for Principal stresses and it might be due to material properties.
For Linear and NL static structural analysis to perform accurate, what material properties that must be defined? in addition to following properties:
E
Poisson's ratio
Bulk and shear modulus
Yield strength
My work is ultimately related to structural steel S275 and S355.
I have spent several days searching for clear answer but didn't find any. And I appreciate your help.
Regards

Also, the analysis model is 3D.

for nonlinear you need the material stress-strain curve, constants for mohr-coulumb or something similar.
are you a student?

Thanks for the reply
I'm a structural engineer, and recently have learned Ansys WB which I'm looking forward to use it as extra verification whenever it's needed.
For NL, I found that ANSYS will accept a NL material if it has as minimum as Tangent modulus and yield strength.
Do you have a source where I can get what you mentioned here: "constants for mohr-coulumb or something similar"
As stated above, I'm mainly using S275 and S355 structural steel.
