Bz. Margolin et al., FATIGUE FAILURE OF NUCLEAR PRESSURE-VESSEL STEELS - I - LOCAL CRITERION OF FATIGUE FAILURE, International journal of pressure vessels and piping, 74(2), 1997, pp. 105-109
Local strain-stress criterion has been formulated relating to fatigue
failure for nuclear pressure vessel steels under low cyclic loading. T
he suggested criterion allows one to predict the fatigue life for tria
xial stress state and non-stationary loading with regard for the maxim
um stress effect. Under the fatigue life calculations on the basis of
the suggested criterion it is not required to introduce any empirical
cumulative damage rules. Comparison of calculated and experimental res
ults has been performed under two-block loading as applied to 2Cr-Ni-M
o-V nuclear pressure vessel steel. (C) 1998 Elsevier Science Limited.
