"And I think if you perform EP analysis, all other requirement such as ratcheting and fatigue must be EP analysis also to be consistent as there is also an approach to this in the code".

To clarify this doubt I have captured a statement in ASME VIII Div. 2 Part 5 section 5.1.1.2 stating:

"If multiple assessment procedures are provided
for a failure mode, only one of these procedures must be satisfied to qualify the design of a component.

Any other opinion is highly appreciated. Corrections are welcome.

Cheers!!!
