Application of the fictitious radius for the calculation of the fatigue life using the elastic-plastic body model

Abstract

ARTICLES YOU MAY BE INTERESTED INAbstract. In this paper, the fictitious radius -according to Neuber's method for determination of stresses at the notch root was used. Next, the fatigue lives of elements of the ring notches were calculated, and then compared with results of experimental tests of S235JR and 42CrMo4+QT steel samples. It has been demonstrated that the fictitious radius strongly depends on the expected fatigue life.
