Based on a previous model dedicated to the prediction of the loading frequency effect on the fatigue endurance of low-carbon steels, the present work elaborates a strategy to extend its application range to medium- and high-carbon steels. From this viewpoint, fatigue tests were newly performed for JIS S45C (0.42%C) steel. Thereafter, the model effectiveness has been discussed on the basis of numerous data reported by other researchers, resulting in an overall correlation coefficient of 0.940. Finally, the model outcomes derived from a dislocation energy viewpoint have presented a good agreement with the experimental trend.

加载频率对结构碳钢疲劳强度的影响：基于位错运动理论的估算和模型的实验验证

基于之前致力于预测加载频率对低碳钢疲劳耐力影响的模型，目前的工作阐述了将其应用范围扩展到中高碳钢的策略。从这个观点出发，对 JIS S45C（0.42%C）钢新进行了疲劳试验。此后，根据其他研究人员报告的大量数据讨论了模型的有效性，得出的整体相关系数为 0.940。最后，从位错能量的角度得出的模型结果与实验趋势非常吻合。
