title = "Characterization of fatigue damage in A36 steel specimens using nonlinear Rayleigh surface waves",
abstract = "This research uses nonlinear Rayleigh surface waves to characterize damage in A36 steel specimens caused by monotonic tension and low cycle fatigue. Fatigue damage produces the increased acoustic nonlinearity that leads to the generation of measurable higher harmonics in the initially monochromatic Rayleigh wave. Tone burst Rayleigh wave signals are generated and detected using a pair of wedge transducers. The experimental results show an increase of acoustic nonlinearity in the early stage of fatigue life and a close relationship between the acoustic nonlinearity and cumulative plastic deformation.",
