A vast amount of research has been carried out towards the goal of quantifying changes related to the fatigue damaging process in materials throughout the fatigue life. However, no recommended practice has been developed for the experimental measurement of fatigue damage before a macroscopic crack has been initiated. Therefore, this paper reviews the existing fatigue damage detection and measurement techniques on the basis of both momentum within the research field and their being considered non-destructive. The techniques are separated into two categories, namely, fatigue crack monitoring and fatigue damage monitoring. The parameters of these techniques, which quantify the physical and mechanical changes of the materials during the fatigue life, were critically reviewed in regard to the mechanism behind the change, limitations, shortcomings, etc. The acoustic emission, hardness, ultrasonic, magnetic and potential drop methods are applicable for in-situ measurements while positron annihilation and X-ray diffraction are more suitable for laboratory assessments. Even though all the revived methods are applicable for metals, acoustic emissions, X-ray diffraction, ultrasonic, strain-based and thermometric methods are also suitable for composites. The reliability, advantages, weaknesses, case/material dependency and applicability of each method are compared and tabulated for making a framework for choosing suitable technique for fatigue crack or damage detection of material or components.

疲劳损伤检测与测量技术综述

为了量化与材料在整个疲劳寿命期间的疲劳破坏过程相关的变化,已经进行了大量研究。然而,在宏观裂纹开始之前,没有为疲劳损伤的实验测量制定推荐的做法。因此,本文在研究领域内的动量及其被认为是非破坏性的基础上回顾了现有的疲劳损伤检测和测量技术。这些技术分为两类,即疲劳裂纹监测和疲劳损伤监测。这些技术的参数量化了材料在疲劳寿命期间的物理和机械变化,并针对变化背后的机制、局限性、缺点等进行了严格审查。声发射法、硬度法、超声波法、磁法和电位降法适用于原位测量,而正电子湮没和X射线衍射法更适用于实验室评估。尽管所有复兴的方法都适用于金属,但声发射、X 射线衍射、超声波、基于应变和测温的方法也适用于复合材料。将每种方法的可靠性、优点、弱点、案例/材料依赖性和适用性进行比较并制成表格,以便为选择合适的材料或部件疲劳裂纹或损坏检测技术制定框架。磁和势降方法适用于原位测量,而正电子湮没和 X 射线衍射更适合实验室评估。尽管所有复兴的方法都适用于金属,但声发射、X 射线衍射、超声波、基于应变和测温的方法也适用于复合材料。将每种方法的可靠性、优点、弱点、案例/材料依赖性和适用性进行比较并制成表格,以便为选择合适的材料或部件疲劳裂纹或损坏检测技术制定框架。磁和势降方法适用于原位测量,而正电子湮没和 X 射线衍射更适合实验室评估。尽管所有复兴的方法都适用于金属,但声发射、X 射线衍射、超声波、基于应变和测温的方法也适用于复合材料。将每种方法的可靠性、优点、弱点、案例/材料依赖性和适用性进行比较并制成表格,以便为选择合适的材料或部件疲劳裂纹或损坏检测技术制定框架。
