Design by analysis rules for pressure vessels and piping such as those contained in the ASME B&PV Code, Section III NB or Section VIII Div. 2, provide requirements to avoid a ratcheting condition under cyclic loading. This paper reviews and compares various related provisions for elastic analysis in Section III NB or Section VIII Div. 2 of the ASME B&PV and compares with other standards, such as the RCC-MR Code. The paper provides recommendations on how the specified requirements should be considered and also discusses cases that need to be addressed in the code.
