摘要

•A DBN-based methodology for dynamic risk analysis of SW fatigue failure during entire life is proposed.•Uncertainty in fatigue damage of SW is analyzed.•The most probable factors contributing to fatigue failure of SW are identified.•Active measures to mitigate the fatigue failure risk during SW's service life are developed.
