The objectives of this review are to identify and present definitions of fatigue and theoretical, conceptual and mechanistic models of fatigue, and to identify the commonly used instruments that measure fatigue in humans and the settings in which they are used. Specifically, the review questions are:
Fatigue refers to the weakening of a material caused by cyclic loads on the material (Ramachandran et al., 2005). Fatigue is the progressive and localized structure damage under a dynamic load. The progress of fatigue can be divided into three stages; i.e., crack initiation, crack growth, and overload failure.
Aug 30, 2019 · 1. A tension stress high enough, but below the tensile strength of the material. 2. A stress variation higher than a material property called “fatigue limit”. 3. A sufficient number of accumulated load cycles.
• Fatigue properties, including the fatigue limit, S-N curves, fatigue diagrams, and also fatigue crack growth are discussed in Chapters 6 to 8. Some prediction problems are discussed in these chapters.
