In materials science, fatigue is the initiation and propagation of cracks in a material due to cyclic loading. Once a fatigue crack has initiated, it grows a small amount with each loading cycle, typically producing striations on some parts of the fracture surface.

24 de sept. de 2020 · Metal fatigue is a type of failure caused by repeated stresses that create microcracks and grow over time. Learn about the different types of metal fatigue, how to design and select materials to prevent it, and how it affects aviation and other industries.
15 de mar. de 2016 · Material fatigue is a phenomenon where structures fail when subjected to a cyclic load. This type of structural damage occurs even when the experienced stress range is far below the static material strength. Fatigue is the most common source behind failures of mechanical structures.
25 de nov. de 2019 · Metal fatigue is one of the subtlest types of metal failures, and one of the most dangerous. Although metal failure can occur from excessive tensile loads, shear loads and impact loads, to name a few, metal fatigue is a failure type that can go unnoticed right up until the point when it is too late.
16 de dic. de 2018 · This report contains a compendium written for a fatigue course at Aarhus University during 2016-2018. It introduces the basic concepts governing fatigue strength of metals and presents associated ...
