Structural fatigue refers to the progressive and localized deterioration of a material or structure caused by repeated loading and unloading cycles over time. This phenomenon can lead to the initiation and growth of cracks, ultimately compromising the integrity and safety of the structure. Factors such as the material properties, design, load frequency, and environmental conditions can influence the rate of fatigue. It is a critical consideration in engineering and maintenance practices to ensure the longevity and reliability of structures.

What is the dafination of endurance limit?
The endurance limit, also known as the fatigue limit, is the maximum stress level a material can withstand for an infinite number of load cycles without failing due to fatigue. Below this stress level, the material is expected to endure cyclic loading indefinitely without developing cracks or experiencing fatigue failure. The endurance limit is particularly significant for materials subjected to repetitive or fluctuating stresses, such as metals in structural applications. It is typically determined through fatigue testing.
What is fatigue in metallurgy?
Fatigue in metallurgy refers to the progressive and localized structural damage that occurs when a material is subjected to cyclic loading, often below its ultimate tensile strength. This phenomenon can lead to the formation of cracks and eventual failure after repeated stress cycles, even if the loads are well within the material's limits. Fatigue is influenced by factors such as material properties, environmental conditions, and the presence of stress concentrators. Understanding fatigue is crucial for designing components that can withstand repeated use without failure.
