I know the properties of material and I don't know have S-N curve. how can I derive the curve with the known properties.
Please help me
If this is for a fatigue analysis involving steel you can define the material in the fatigue study to "Derive from material Elastic Modulus" and the program will create an S-N curve to use in that study.
Further to what Ryan mentioned, please be aware that the maximum number of S-N curve data points that software can take for fatugue analysis is 20. Thoughts it may be useful.
