FCGRs in NR and TMCP S355 steels in seawater
A
similar study described in Section 3 was carried out in SW . The
authors assessed the FCG resistance of J2N, G8 and G10 given in
Table 2 in SW . The details of the experimental procedures have
been discussed in Refs [22][36][67]. The experimental
results are shown in Fig. 16. Three corrosion fatigue crack growth rate
(CFCGR ) curves, obtained at 12kN, 9kN and under 0.3Hz, for the
J2N studied by Adedipe [53] (abbrev. ‘Ade’) were plotted from the
data extracted from \(a\) vs. \(N\) curves given in Ref [53]. In the
present study, one test on the J2N was performed at 9kN, 0.3Hz, R = 0.1
to validate the results obtained in the Adedipe’s study. Mehmanparast
[59] studied CFCG in G8 under similar loading conditions and
at three different test locations noted as (A3, A4), (B3, B4) and C3. In
identifying the experimental samples, the prefix gives the steel
subgrade – J2N, G8, G10, followed by S (S = sinewave),
Pmax (maximum load), F (frequency, followed by the
frequency value) and the last is the test centre for the Mehmanparast
[59] study. All the tests were performed in SW and under
sinewave.
