Figs.5: Comparisons of experimental LCF results for SSFS test with that
predicted using the UVP model, (a) Hysteresis loops of the calibrated
Chaboche UVP model and cyclic experiment with the first loop, and (b)
Comparison of the maximum stress evolution with cycles illustrating
softening in FV566 at 600 °C, a strain-range of ± 0.7%, and applied
strain-rate of 0.01%s-1.
