本章解释了 FML 中的疲劳损伤增长现象，并提供了基于单个断裂现象描述损伤增长的理论。讨论了各种几何校正因子的有效性。在 FML 中观察到的不同厚度方向的裂纹几何形状和裂纹路径均针对轴内和离轴载荷进行了解释。最后，讨论了变幅载荷和恒幅载荷之间的关系。
This chapter explains the fatigue damage growth phenomena in FMLs, and provides theories to describe the growth of damage based on the individual fracture phenomena. The validity of various geometrical correction factors is discussed. The different crack geometries through-thickness and the crack paths, observed in FMLs, are explained for both in-axis and off-axis loading. Finally, the relation between variable amplitude and constant amplitude loading is covered.
