Abstract

The fatigue crack growth rate dl/dN characteristics of prestrained carbon steel were studied. In this study, the relationship between the ultimate tensile strength σ_B of prestrained specimens and dl/dN was the focus. Under the conditions of large-scale yielding, there is a correlation between dl/dN and σ_B where dl/dN versus σ_aⁿ l characteristics are modified by σ_B, regardless of the degree of prestrain. Under the conditions of small-scale yielding, although σ_B affects dl/dN, σ_B does not correlate strongly with dl/dN in comparison with the case under the conditions of large-scale yielding.
