The paper, after analysis of a large experimental data base, shows that, depending on the material, the effect of defect on the fatigue limit should be described through 5 major parameters:

Size, Type, Position, Morphology and Loading.

A fatigue criterion describing the effect of the defect through the local stress gradient is discussed and the identification procedure shows that each of the 5 major parameters can be taken into account. This criterion is included in a global modelling strategy starting from either µCT image or process simulation of the defect population and finishing with a defect size map at the scale of the structural component.

缺陷疲劳：尺寸、类型、位置、形态和载荷的影响

该论文在对大型实验数据库进行分析后表明，根据材料的不同，缺陷对疲劳极限的影响应通过 5 个主要参数来描述：

尺寸、类型、位置、形态和负载。

讨论了通过局部应力梯度描述缺陷影响的疲劳准则，识别程序表明可以考虑 5 个主要参数中的每一个。该标准包含在全局建模策略中，从缺陷群的 μCT 图像或过程模拟开始，并以结构组件的尺度上的缺陷尺寸图结束。
