The stress gradient corrected peak stress is used with the presented S N curves for estimating the fatigue life of fatigue tested notched specimens with typical subsea design features.
In this chapter the editor of the handbook would like to stress correct problem formulation, and especially correct DE, as crucial issues.
The methodology of calculating SCFs is verified based on the FE analysis of details with derived target hot spot stress and corrected SCFs are thus obtained.
For the bi-modal microstructure, the Kitagawa–Takahashi diagram provides a basis for describing the threshold conditions for FOD-induced HCF failures, in terms of the stress concentration corrected smooth-bar fatigue limit for small crack sizes and the worst-case threshold for larger continuum-sized cracks.
During stress, fibrinogen corrected arithmetically was marginally less than fibrinogen corrected with baseline plasma reconstitution and not significantly different than fibrinogen corrected with saline reconstitution.
Examples of enriched GO categories after 1-day thermal stress conditions (corrected P-value by Benjamini P < 0.001) included 27 biological process (BP) categories, 13 molecular function (MF) and 9 cellular component (CC) categories.
The data were in turn converted to Hencky's (true) strain and corrected stress using equations (2) and (3), according to the procedure used by Mao et al. [ 39].
Strains and stresses are corrected after the recovery to satisfy the top and bottom boundary conditions of the laminated composite shell or panel.
Correspondingly, for FOD-initiated failures, where the critical condition for HCF must be defined in the presence of microstructurally small cracks, the Kitagawa–Takahashi diagram, with the limiting conditions of the stress-concentration corrected 107-cycle fatigue limit and the "worst-case" ΔKTH fatigue threshold, is proposed as a basis for design against FOD-induced HCF failures.
Mean stress effect is corrected with several mean stress parameters and a shift factor of Arrhenius type is defined to characterize the effect of temperature on fatigue life.
