摘要: Abstract The partitioning point dividing ΔK into ΔKeff, denoted Kop, was determined for A1 7475-T7351 and the Ni-base alloy Nicrofer 5219 Nb annealed. experimental testing technique used relies only on fatigue crack propagation behavior, i.e. whether a can propagate or not propagate. It found that Kop is steadily increasing function of R-ratio Kmax up to an upper bound value depending Kmax. This as Kop(max. value). annealed only; no exists this material. Kop/Kmax both materials, locus (max. value) are represented in form polynomial equations.
