WebJun 1, 2024 · Using a modified formula of Paris law, a researcher [32] proposed a power law for the fatigue crack growth relationship with Δ K eq, which is specified as (3) da dN = C ( Δ K eq) m. From Eq.3, for a crack increment, the number of life cycles of fatigue may be predicted as: (4) ∫ 0 Δ a da C ( Δ K eq) m = ∫ 0 Δ N dN = Δ N. 3.
