Sažetak
A particular empirical strain rate modified (SRM) rule of damage accumulation in the creep-fatigue interaction regime has been supported with Chaboche’ s uniaxial viscoplastic constitutive mode to predict lifetime under non-stationary loading at high temperatures. The suitability of the proposed couple to extrapolate lifetime predictions to various cycling loading conditions other than those of a few fatigue tests required for the calibration of the SRM rule has been verified for IN 738 LC superalloy at 850 °C.
