Originální abstrakt

This work presents the application of the acoustic emission technique for detection and characterization of early fatigue damage. Specifically various manifestations of the localized plastic deformation that is the precursor of microcrack formation. A nuclear Cr-Ni-Mo-V low-alloy steel has been chosen for this study. The acoustic emission signal has been correlated with the defect formation mechanisms and the registration of loading (resonant) frequency changes of the tested specimen taken by RUMUL fatigue machine. The work is focused on the analysis of the acoustic emission signal during opening and closure half-cycle.
