Abstract
This paper describes simplified methods for estimating the strain range produced in notched components under thermal loading for the purpose of fatigue, creep, and creep-fatigue damage assessment. The methods presented are based on the previously proposed stress relaxation locus and the elastic follow-up factor combined with a newly proposed method for evaluating primary-plus-secondary stress limit. The procedures contained in the methods do not need the linearization of stresses. The proposals are validated by performing elastic-plastic finite element analysis of notched components subjected to cyclic thermal loading.
