WebIt discusses the fatigue crack growth rate (FCGR) testing that consists of several steps, beginning with selecting the specimen size, geometry, and crack length measurement … When a constant range of cyclic stress, Δσ (= σmax - σmin), is applied to a cracked structure, stable fatigue crack growth can occur at stress levels well below the yield stress of the material. In fact, the range of the stress intensity factor ΔK, where ΔK = Kmax − Kmin in a cycle may also be well below the materials … See more Let us now consider the crack tip plastic deformation in more detail, as it is the driving force for crack growth. For a crack under cyclic loading, the plastic size is related to the stress intensity factor at the maximum load, … See more As discussed earlier, fatigue life prediction for constant amplitude loading is reasonably straightforward, provided the fatigue crack growth constants are known. However, the majority of engineering structures are … See more The term damage tolerance has a variety of meanings, but normally refers to a design methodology in which fracture mechanics analysis is used to predict crack growth life and quantify inspection intervals.
