I have a Question that needs some clarification please.
Correct me if I am wrong but it seems that for most materials there isn't a S-N curve defined to it.
I know that if you go into your material database some of the materials has (ss) next to them which is the stress strain curve, and then only a few has (SN) next to the material, which is the S-N curve.
Now my question is, why aren't the SN and SS curves assigned to all the materials?
It seems to me that, if for instance you need the S-N curve for Alloy steel that you must manually punch in the values and create the S-N curve.
There is also no (SN) next to any Steel materials in your database.
I know you also have a database for a few S-N curves as soon as you create a fatigue study. but this is also limited to only a few materials.
Any advice or feedback would be much appreciated.
