Wzrost pęknięć zmęczeniowych w stali 18G2A przy obciążeniach stałoamplitudowych i po pojedynczych przeciążeniach.
Języki publikacji
Abstrakty
Effects of specimen thickness and stress ratio on fatigue crack growth and crack closure level under constant amplitude loading and after the single overload have been studied experimentally for a structural steel (18G2A). The corresponding crack growth data from the fatigue tests have been presented and evaluated. The experimental trends have been compared to those reported in the literature for various steels. The ability of the effective stress intensity factor range based on crack closure measurements to correlate the observed crack growth response has been investigated.
Przedstawiono wyniki badań eksperymentalnych nad wpływem grubości próbki i współczynnika asymetrii cyklu na wzrost pęknięć zmęczeniowych oraz poziom zamykania się pęknięcia w stali 18G2A przy obciążeniach stałoamplitudowych i po pojedynczych przeciążeniach. Znalezione trendy eksperymentalne porównano z opublikowanymi wynikami innych prac otrzymanymi dla różnych stali. Zbadano możliwość korelacji prędkości wzrostu pęknięć ze wszystkich eksperymentów przy pomocy efektywnego współczynnika intensywności naprężeń opartego na wynikach pomiarów zamykania się pęknięcia.
