Fatigue damage evaluation in A36 steel using nonlinear Rayleigh surface waves (2012, background): “A similar leveling off or ‘‘saturation’’ of the measured acoustic nonlinearity later in the fatigue life (after an initial increase) has also been observed in the results from specimens in other materials, such as a nickel-base superalloy [4] and aluminum [5].”
Ultrasonic waves for materials evaluation in fatigue, thermal and corrosion damage: A review (2019, unknown): “It has been demonstrated [18] [19] [20] that NNDT have higher sensitivity in the detection of small damage than classical linear techniques [21] [22].”
