Implication

Observational analysis reveals effects of loading history and environment on fatigue in 316L steel, highlighting shortcomings in existing methodologies.

Key Points

Data indicates that reducing the NUREG transference factor on stress to 1.4 may better reflect actual conditions, and more analysis is needed for cycle factors.
Comprehensive investigation into how loading history, environment, and surface finish impact fatigue was conducted using variable amplitude testing on 316L stainless steel.
The research emphasizes inconsistencies in current design methodologies, recommending a reevaluation of stress-based mean stress corrections.
Findings support the alternative approach proposed by the Japanese Subcommittee on Design Fatigue Curve, suggesting necessary modifications to existing design curves.
