  • materjali või detaili suure tsüktilte arvuga väsimus pingetel allapoole voolepiiri (taval. tsüklite arv enam kui 104) (vt väsimus; vrd madaltsükliline väsimus)
  • fatigue that occurs at relatively large number of cycles; the arbitrary, but commonly accepted, dividing line between high-cycle and low-cycle fatigue is considered usually to be about 104 cycles (see: fatigue; compare: low-cycle fatigue)
    Good to know
    • In practice, the distinction between high-cycle fatigue and low-cycle fatigue is made by determining whether the dominant component of the strain imposed during cyclic loading is elastic (high cycle) or plastic (low cycle), which in turn depends on the properties of the metal and on the magnitude of the nominal stress.

Usage examples
  • Eristatakse paljutsüklilist (pingetel alla voolepiiri) ja vähetsüklilist väsimust (pingetel üle voolepiiri) vahel. Paljutsüklilise väsimuse korral ületab koormustsüklite arv taval. 104 tsüklit ja selle all kannatavad kõik pöörlevad ja vibreerivad süsteemid (rattad, võllid, masinaosad), ...
