Implication

This research demonstrates differences in fatigue life for hollow and solid specimens in LWR environments, implying significant implications for environmental assisted fatigue assessments.

Key Points

Fatigue tests show that hollow specimens exhibit different fatigue lives compared to solid specimens, which impacts safety analyses.
Initial findings indicate differences in crack propagation stages, with cracks initiating sooner in hollow specimens due to lower wall thickness.
Finite Element Analysis supports the hypothesis that internal pressure contributes to the Von Mises strain in hollow specimens.
This research may bridge the gap in environmental assisted fatigue assessments for nuclear pressurized water reactor components.
