tsüklitugevus
Tsüklitugevus refers to the capacity of a material to withstand repeated stress or strain cycles without fracturing. This phenomenon is critical in the design and analysis of components subjected to fatigue, which is the progressive and localized structural damage that occurs when a material is subjected to cyclic loading. The load does not have to be above the material's yield strength for fatigue to occur.
The study of tsüklitugevus is vital in engineering fields, particularly in aerospace, automotive, and civil engineering,
Common methods to assess tsüklitugevus involve fatigue testing, where samples are subjected to controlled cyclic loads
