Gents,

I have one question about the annex 3-F.

What fatigue curve I need to use for the calculation of a high pressure sphere that have a weld joint in the middle of the hemisphere head? 3-F.1 or 3-F.2?

Also when I can use the both cases? I understand that the curve should be used to calculation of supports. That is correct or not?

Thanks

Kind Regards,

GFJ

 
What's the UTS of the material. Shouldn't you be using the Structural Stress Method for a welded joint?
