The EVMS criterion is a simple, but very powerful tool to estimate fatigue damage with time domain analysis of simulated stress histories, or frequency domain evaluation by spectral methods.
Thermal fatigue experiments were induced by thermal mismatched stress and thermal fatigue with holding time.
In Bhattacharyya and Fries (1982), the identical approach in Birnbaum and Saunders (1969a) was viewed as a Wiener process of accumulated fatigue in time (with positive drift parameter μ and diffusion constant τ 2), and this leads directly to an I-G distribution.
Results from the random intercept-slope model demonstrated that the overall trend (or slope) for AE fatigue was not statistically different from 0, indicating no significant change in AE fatigue over time with sunitinib treatment (Fig. 3).
Results from the repeated-measures model demonstrated some fluctuations in AE fatigue over time with sunitinib treatment (Fig. 3), but the differences were small and most pairwise comparisons of the cycle mean values (with the exception of one value) were not statistically significant, indicating that the mean values at every cycle were actually not different from one another.
Fatigued, with little time to prepare, the two favorites, France and Argentina, exited meekly in the first round.
However, we were unable to describe the trajectories that showed an increase in fatigue over time (increased exertion fatigue with mild offset, increased exertion fatigue with moderate offset, and increased general fatigue with mild offset).
Baseline sicca symptoms correlated with higher fatigue both at baseline and with increasing fatigue over time.
A statistically significant difference in fatigue over time was reported, with ECAM participants reporting a greater decrease in fatigue over time compared to control participants.
I was shaking with fatigue by the time we arrived.
This paper outlines a new efficient approach for long-term riser fatigue analysis, in conjunction with time domain simulations.
