PRESENT WORK
The present work is an extension of this model to predict the fatigue
lifetime of un-notched round specimens made of a ferrite-pearlite
0.4C-70/30 carbon steel in the cases of (a) two-step fully reversed
loading with different sequences and (b) repeated application of fully
reversed loading blocks.
Table 1 Experimental parameters of (a) two sets of two-step loading
tests; (b) repeated two-step loading block tests.
