    How come BPVC S-N curves show stress amplitude greater than UTS

    Hi TGS4, Thanks for your reply and thank you for taking the time to explain it in multiple ways, that definitely helped. It seems like this first section of the curve where stress is above yield just wouldn't be applicable since the elastic relationship wouldn't hold here. Do engineers...

    How come BPVC S-N curves show stress amplitude greater than UTS

    Hi there, I've been racking my brain on this for a while so it's time to seek some advice from others in the field. I'm getting up to speed with using the BPVC fatigue calculations in BPVC Section VIII Div 2. One thing I can't reconcile is how come the S-N curves in the BPVC show a stress...
