Materiaalisidontaa
Materiaalisidontaa, or material fatigue, refers to the progressive and localized deterioration of a material caused by cyclic loading or repeated stress over time. This phenomenon is a common concern in engineering and construction, as it can lead to cracks, fractures, and ultimately, failure of structural components. Fatigue occurs even when the applied stresses are below the material’s ultimate tensile strength, making it a critical consideration in the design of machinery, bridges, aircraft, and other load-bearing structures.
The process begins with microscopic cracks that develop at stress concentrators such as surface imperfections, welds,
Understanding fatigue is essential for predicting lifespan and ensuring safety. Engineers employ fatigue testing, often involving
