Implication

Research shows that stress concentration and environmental factors affect fatigue life in 316L stainless steel, indicating the need for improved evaluation methods.

Key Points

Fatigue life increased beyond predictions from standard mean air curves due to notch effects and environment.
Notch radii of 0.5 mm and 2 mm were evaluated, resulting in stress concentration factors of approximately 4 and 2.6.
Finite element analyses guided test design and load evaluations to achieve specific strain amplitudes at notch tips.
Initial tests in air and PWR environments aim to determine impacts of both stress concentration and environmental conditions.
