Abstract

A simplified formula for deriving full range S–N curves of steels with ultimate tensile strength <1400 N/mm2 is proposed by combining empirical formulae and a mathematical function. The salient features of the formula proposed are that it describes the fatigue S–N curve from the first cycle up to the gigacycle region in a single function and that the monotonic test based material parameter needed in this formula is only the Brinell hardness. Fatigue life predictability of the proposed formula is verified using experimental data of smooth and notched specimens tested under various stress ratios.
