Abstract
In this paper, a simplified method is proposed for estimating the strain range produced in notched components under thermal loading for the purpose of assessing fatigue, creep, and creep-fatigue life consumptions. The proposed method is based on the previously proposed stress redistribution locus (SRL) and elastic follow-up factor, which are combined with a new method for evaluating the primary-plus-secondary stress limit. The proposed method does not require the linearization of stresses and was validated by performing elastic-plastic finite element analysis (FEA) of notched components subjected to cyclic thermal loading.
