What is a structural fatigue?

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.
