Hello,

A weld was designed and tested to a BS 7608 E curve and now with the values obtained, number of cycles I wanted to calculate the target number of cycles to BS 7608 D curve but I am a bit lost.

How do I calculate the target number of cycles for a the D curve per BS 7608 (I have the nominal stress range)?

Thank you.
