“…To address this issue, a considerable amount of research has been conducted to investigate the uncertainties encountered during fatigue testing. For instance, Santiago analyzed the effect of surface treatment of test specimens on fatigue test results, 3 Gao discussed the impact of damage depth at different stages on fatigue strength, 4 and Bao studied the influence of defect size and location in the test specimen on fatigue life 5 . Gao 6 conducted experiments to derive the impact of internal and external factors on the residual strength of materials.…”

Fatigue testing is a crucial technique for assessing the fatigue performance of materials and components. However, the testing process often involves numerous uncertainties, such as variations in part roughness and size, and the collected data typically constitutes small samples. This paper proposes an improved bootstrap method with cycle of uncertainty to address the limitations of traditional bootstrap methods in estimating uncertainties in small sample sizes. The proposed method was applied to estimate the effect of surface roughness and common normal size on fatigue tests, resulting in improved estimation accuracy. The research contributes to the development of improved methods for fatigue life estimation, which has practical implications for mechanical component design and optimization.

“…Its good corrosion resistance can reduce the degradation of mechanical properties caused by corrosion during service. Q450NQR1 steel is a popular weathering steel that is used extensively in high-speed train structures, where the service environment is not always ideal, such as the wheel stick-slip and the resulting flats, which results in corresponding cyclic loads [1]. Its fatigue life has a significant impact on the safety of high-speed trains.…”

“…Thus, the objective of this paper is to investigate the feasibility of adopting Vickers, low-force Vickers and Brinell hardness measurements as a means of assessing accumulated fatigue damage. Herein, feasibility is considered from the perspective of adopting the change in hardness as a continuous damage monitoring technique for structural health monitoring, the latter being about the consequence of the local residual stress (LRS), which will be left at the surface near the indentation and the indentation itself, which effectively will be a notch (Gao et al, 2021). In this regard, it should be noted that both notches and tensile residual stresses are commonly known to reduce the fatigue strength of a material, compared to its notch-and LRS-free counterparts (Li et al, 2022).…”

PurposeBrinell, Vickers and low-force Vickers hardness measurements are herein adopted to investigate and quantify the fatigue damage evolution in specimens made of S355J2+AR ferritic pearlitic steel. Though nano and microhardness measurements have been well adopted, they require a strict preparation routine, whereas macroscopic hardness measurements are not as stringent.Design/methodology/approachThe feasibility of adopting macroscopic hardness measurements as a means of measuring fatigue damage is investigated through a combination of experimental tests and finite element analyses with both Brinell and Vickers hardness indenter.FindingsIt is found that the Brinell hardness measurements method seems more feasible, regarding finding a continuous and significant change during the fatigue life, in comparison to both Vickers and low-force Vickers. Thereafter, the question regarding the feasibility of the hardness measurements as a method of assessing accumulated fatigue damage in situ is discussed.Originality/valueMuch work has previously been performed towards correlation of the micro and nano hardness indentations, which generally has stringent preparation requirements before testing. Herein, the adoption of macroscopic hardness measurements as a means of assessing accumulated fatigue damage is considered both experimentally and theoretically.
