Web24 dec. 2001 · This part focuses on a crack closure and fatigue analysis of the data presented in Part I. A plasticity-induced crack-closure model was used to correlate large-crack growth rate data to develop the baseline effective stress intensity factor range (Δ Keff ) against rate relations for each material, ignoring the large-crack threshold. Web1 apr. 2014 · Crack closure provides an effective correction to the crack driving force, which facilitates more accurate prediction of long crack and small crack fatigue …
WebThe crack opening function, f for plasticity-induced crack closure has been defined by Newman 3. The threshold stress intensity factor range in Eq. (1), DKth, is … WebFurthermore, the biogenic formed hydrogen sulfide can cause sulfide stress cracking of the iron (Figure 2D). FeS may, temporarily, act as a protective action against iron corrosion as it is strongly adhered to the metal surface through the direct reaction of the dissolved sulfide with metallic iron (Newman et al., 1992; Sun and Nešic, 2007).
