Fatigue Assessment - Elastic-Plastic Analysis SS316

[nashki]

Dear Members,

I am working on fatigue assessment according to ASME Section VIII Division 2 5.5.4, for Stainless Steel Type 316.

During development of the material model, I realized that in Annex 3-D Table 3-D.2/2M does not provide the n_CSS and K_CSS for Type 316 material.

Does anyone have information how to obtain both parameters for SS316?

I ran into the same issue before. Ended up using values from literature and some references to ASME Section II Part D. You might need to check papers on cyclic stress-strain behavior for SS316, or reach out to material suppliers—they sometimes have that data.

May I direct you to API/ASME 579-1, Para 2E.4- Cyclic Stress-Strain Relationships?

Yes, I have that paper. But in that paper, they have selected Type 304 Annealed at 20degC for the value n_css and K_css, to evaluate type 316 stainless steel.
Do you think I can follow the same method to evaluate type 316SS?

Hi, thank you for your information. Can you please share the reference?

Hi, thank you for the reference. I can find the formula to calculate the K_css and n_css, in the Para 2E.4.2.1.
Do you think we can use that formula for fatigue assessment according to ASME VIII D2?
