Low-cycle fatigue

Low-cycle fatigue (LCF) is a type of fatigue that occurs in materials subjected to repeated or cyclic loading, leading to plastic deformations at an upper range of strain levels. It is typically characterized by a relatively low number of loading cycles (often less than 10,000 cycles) compared to high-cycle fatigue, which occurs at much lower stress levels and involves a much higher number of cycles, often exceeding one million.
