A Method to Determine the Transition Point of Fatigue Crack Growth Rate from Near-Δ to Paris Regions

CODEN: JTEVAB

Abstract

The transition point of fatigue crack growth (FCG) between the near-ΔKth and the Paris regions is an important value to study fatigue behavior. This study introduces a curve-fitting technique to identify this point for nickel-based superalloy U720 with stress ratio of R = 0.1 at room temperature. The value of ΔKth under these conditions is also determined.
