Multiscale Correlation Effects during Fatigue Damage Evolution Observed by Surface Roughness Analysis.
Original language description
Periodic and random surface roughness of cyclically loaded specimens of ferritic and austenitic steels was measured using new optical method based on laser light scattering on rough surfaces. Measured dependencies of autocorrelation length of surface T on relative number of cycles N/Nf indicate an onset of a stable extrusion/intrusion relief on the specimen surface caused by fatigue process. In addition to this, the qualitative and quantitative investigations of surface relief formation and evolutiion on Al single crystal thick films rigidly attached to specimens under cyclic tension were carried out by optical microscopy with the CCD camera in online regime, local investigation by X-ray method and analysis of interference fringes.
