The paper addresses the problem of analysis of cyclic loading for creep and ratcheting. The approach is to use cyclic elastic-plastic analysis to generate shakedown and ratcheting boundaries or reference stresses. These provide bounds to creep damage and strain accumulation, which are independent of time and temperature. Two cases are analyzed, which have different behavior from the Bree problem, which forms a basis for ASME IIINH creep strain design rules.
