Abstract

Highlights: A criterion for fatigue assessment of high strength steels is proposed. The influence of non-metallic inclusions on fatigue life is taken into account. The Carpinteri et al. criterion is used in conjunction with the area -parameter model. An experimental campaign is analysed to evaluate the criterion accuracy. Abstract: In the present paper, a criterion for fatigue assessment of high strength steels is proposed, where the influence of non-metallic inclusions on fatigue life is taken into account. To such an aim, the Carpinteri et al. criterion is used in conjunction with the area -parameter model by Murakami and Yanase. An experimental campaign available in the literature is analysed to evaluate the criterion accuracy.
