Measurement-driven, model-based estimation of residual stress and its effects on fatigue crack growth. Part 2: Fatigue crack growth testing and modeling

•Fatigue cracks in samples with residual stress (RS) under constant amplitude load.•Growth of complex, two-dimensional cracks analyzed by multi-point fracture mechanics.•Test data from potential drop, quantitative fractography, and digital photogrammetry.•Residual stress from model estimates or measurements included or ignored.•+26% to −14% error in life if RS included; +60% error (anticonservative) if RS ignored.
