Abstract

This study presents the description of fatigue damage in the context of the statistical process control paradigm. The quality control approach that was used in the analysis was needed in order meet the requirements as well as improving the fatigue damage caused by variable amplitude loading. The methodology discussed in this study is enabling to reduce variability with the specification limits at three standard deviations on both side of the mean value. This concept was used to comparing three ARIMA models that have been previously found based on potential capability value (Cp) and mean Squared Deviation (MSD). The assumption was made when the process reached the upper and the lower control limits in term of reducing the variability that was described by a variable amplitude fatigue loading. A successive three-sigma concept was then applied and developed on to this type of loading and it purpose was to detect the variation. Finally, it is suggested that the three-sigma concept provided a good platform for analyzing the fatigue damage in the aspect of the durability assessment.
