Fatigue failure occurs due to repeated loading and unloading of materials from "summary" of Stress and Strain by Winthrop Dickinson Means
Fatigue failure is a common phenomenon in materials subjected to repeated loading and unloading. This type of failure occurs when a material is exposed to cyclic stresses over time, leading to the development of cracks and ultimately structural failure. The process of fatigue failure is insidious, as it may not be immediately apparent and often occurs without warning. When a material is subjected to cyclic loading, the stress levels fluctuate between maximum and minimum values. As the material is loaded and unloaded repeatedly, micro-cracks begin to form and propagate within the structure. These cracks may initially be small and undetectable, but over time they can grow in size and eventually lead to catastrophic failure. The development of fatigue cr...
