WebThe chief difference between high cycle and low cycle fatigue is the number of cycles to failure. Transition between LCF and HCF is determined by the stress level, i.e. transition between plastic and elastic deformations. High cycle fatigue require more than 10 4 cycles to failure where stress is low and primarily elastic.
